AB  - Y0.8−xGdxF3 :Yb/Er mesocrystals with a biocompatible surface and diverse morphological characteristics were successfully synthesized using chitosan-assisted solvothermal processing. Their structural properties, studied using X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning and transmission electron microscopy and energy dispersive X-ray analysis, were further correlated with the up-conversion emission (λexc = 976 nm) recorded in function of temperature. Based on the change in the visible green emissions originating from the thermally coupled 2H11/2 and 4S3/2 levels of Er3+, the corresponding LIR was acquired in the physiologically relevant range of temperatures (25–50 ◦C). The detected absolute sensitivity of about 0.0042 ◦C −1 , along with the low cytotoxicity toward both normal human lung fibroblasts (MRC-5) and cancerous lung epithelial (A549) cells, indicate a potential for use in temperature sensing in biomedicine. Additionally, their enhanced internalization in cells, without suppression of cell viability, enabled in vitro labeling of cancer and healthy cells upon 976 nm laser irradiation.

AB  - Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP–OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules. Considering that the photocatalytic activity of the cotton-based TiO2 and TiO2/Ag samples was practically imperceptible, it can be assumed that the synthesized Ag NPs act predominantly as electron traps in the double-loaded synthesized system.

AB  - Hydrogels  have  unique  properties  and  many  potential  applications,  particularly  in  medicine and biotechnology. Gel porosity and swelling properties, stability, and biocompatibility are charac-teristics that are widely variable and easily adjusted. Stimuli-responsive or intelligent hydrogels are a  class  of  thesematerials  that  shows  a  significant  response  to  small  changes  in  the  surrounding environment.  Poly(N-isopropylacrylamide)  (PNiPAAm)  is  the  best-known  thermosensitive  polymer with a well-defined volume phase transition temperature (VPTT) around 32C. On theother hand, silver  nanoparticles  (AgNPs)  have  been  the  subject  of  intense  interest  due  to  their  size-dependent optical,  catalytic,  and  electronic  properties  as  well  as  remarkable  antimicrobial  potential.  Within the last decade, scientists have demonstrated that anisotropic AgNPs can be synthesized in a controlled  manner  and  that  these  materials  exhibit distinctively  different  physicochemical  properties from  their  spherical  counterparts.  A  significant  challenge  that  scientists  face  is  establishing  how thesenanoparticles  can  be  used  in  a  wider  spectrum  of  practical  applications.  Therefore,  we  pre-sent  a  simple,  straightforward  two-step  synthesis  of  AgNPs/PNiPAAm  hydrogel  nanocomposites that  includes  the  chemical  formation  of  both  spherical  and  triangular  AgNPs,  followed  by  gamma irradiation-induced  PNiPAAm  crosslinking  in  the  presence  of  nanoparticles.  The  gamma  irradia-tion technique merges sterilization and synthesis in a single technological step, optimizing the pro-cess  and  opening  up  a  wide  range  of  innovative  biomedical  applications.  The  formation  of  stable and uniformly distributed AgNPs in the polymer was confirmed by UV-VIS spectroscopy, while the network porous sponge-like structure was observed by SEM analysis. Physicochemical characteri-zation  was  performed  by  examining  the  swelling  and  deswelling  processes  in  water  at  25C  and 48C,  respectively.  In  addition,  AgNPs  were  shown  to  have  an  effect  on  VPTT  values.  Our  main goal is to investigate how different morphologies of AgNPs affect the physicochemicalproperties of nanocomposite samples, considering the potential applications and the ongoing need for the wide-spread use of biocompatible materials

Posebno je interesantna oblast “inteligentnih“ hidrogelova, odnosno materijala koji reaguju na spoljašnje stimulanse i pokazuju značajanu fizičku ili hemijsku promenu pri malim promenama u okruženju. Poli(N-izopropilakrilamid) (PNiPAAm) je najpoznatiji termosenzitivni polimer sa jasno definisanom temperaturom faznog prelaza (VPTT) od oko 32°C. S druge strane, nanočestice srebra (AgNPs) poseduju optička, katalitička i električna svojstva koja se mogu modifikovati promenom njihove veličine i oblika a imaju i izražen antibakterijski potencijal, pa su stoga, poslednjih decenija intenzivno proučavane. Pokazano je da se anizotropne nanočestice srebra mogu kontrolisano sintetisati sa fizičkohemijskim svojstvima različitim od sfernih analoga, pri čemu su značajna istraživanja usmerena na njihovu praktičnu primenu. Zbog svega navedenog, u okviru ovog istraživanja biće izvedena jednostavna dvostepena sinteza AgNPs/PNiPAAm hidrogel nanokompozita koja uključuje hemijsko formiranje sfernih i trouglastih AgNPs u prvom koraku, a zatim gama-indukovano umrežavanje NiPAAm-a u prisustvu ovih AgNPs. Tehnika gama zračenja objedinjuje sterilizaciju i sintezu u jednom tehnološkom koraku čime se proces optimizuje i otvara širok spektar inovativnih biomedicinskih primena. Formiranje stabilnih i uniformno distribuiranih AgNPs unutar matrice hidrogela potvrđeno je UV-Vis spektroskopijom, a porozna sunđerasta struktura polimerne mreže SEM analizom.

AB  - Hydrogels possess distinctive characteristics that can be tailored to meet specific needs, especially in the field of biosciences, which is continuously expanding and advancing. Adjustability of gel porosity, followed by tunability of swelling properties, environmental responsiveness, and stability, are properties that are easily adjusted, offering researchers and engineers the flexibility to fine-tune these properties to suit the specific requirements of diverse applications. As a result of environmental responsivity, one class of these materials emerged, referred to as stimuli-responsive or smart hydrogels. Such hydrogels can change their properties in response to specific external stimuli or environmental conditions in a controlled and reversible manner. Depending on the specific type of smart hydrogel, this feature can enable targeted drug delivery, tissue engineering, and controlled release systems while maintaining their biocompatibility. Poly(N-isopropylacrylamide) (PNiPAAm) is a thermosensitive polymer with a well-defined volume phase transition temperature (VPTT) around 32°C. Conversely, silver nanoparticles (AgNPs) continue to preserve academic interest due to their size-dependent optical, catalytic, and electronic properties, as well as their significant antimicrobial potential. One of the primary obstacles encountered by scientists is establishing the broader range of practical applications of AgNPs as well as improving the existing ones. Optimizing their properties often involves controlling size and shape, stability, and surface properties. In order to determine how anizotropic Ag NPs alter and influence the physicochemical properties of PNiPAAm we present a simple, straightforward two-step synthesis of AgNPs/PNiPAAm hydrogel nanocomposites. This method involves the chemical synthesis of both spherical and triangular AgNPs, followed by the crosslinking of PNiPAAm through gamma irradiation in the presence of nanoparticles. The validation of employing gamma irradiation is based on the fact that this technology integrates the processes of sterilization and synthesis, resulting in a consolidated technical step that enhances efficiency and enables the exploration of numerous innovative biomedical applications. The porous sponge-like structure was observed by SEM analysis, while the formation of stable and uniformly distributed AgNPs in the polymer was confirmed by UV-VIS spectroscopy. Swelling and deswelling processes were performed in water at 25C and 48C, respectively. In addition, AgNPs were shown to influence VPTT values. The primary objective of this study is to examine the correlation between various morphologies of AgNPs and the physicochemical characteristics of nanocomposite samples. This investigation considers the possible uses and the current demand for the extensive utilization of biocompatible materials.

AB  - A  calling  need  for  environmental  protection  is  not  abating  and  high  demands  have  been  set for  the  current  topic  that  deals  with  applied  technologies  for  removal  of  organic  pollutants.  The AOPs  appear  to  be  one  of  the  most  effective  processes,  where  heterogeneous  photocatalysis  using efficient  UV  light-harvesting  TiO2nanocrystals  has  unquestionably  become  one  of  the  most  com-monly used process for dyes degradation treatment. Limited photocatalytic efficiency of TiO2under sunlight  illumination  was  overcame  bycoupling  with  polyaniline  (PANI)  as  notably  investigated conductive polymer. Reducing the level of e-/h+recombination in TiO2and photosensitized proper-ties of PANI was the basis for creation of new functional PANI/TiO2nanocomposites. Such hybrid functional  nanomaterials  consisting  of  conductive  polymers  and  dissimilar  nanocrystals  manifest the  unique  properties,  usually  not  characteristic  of  independent  componentsbut  their  synergistic effect. Series of developed functional nanocomposites based on PANI and colloidal TiO2nanoparti-cles  (NPs)  (TP),  carbonized  PANI  and  colloidal  TiO2NPs  (TPC)  and  carbonized  PANI  and  TiO2nanotubes (NTs) (TTPC) by the efficient and harmless synthesis pathways are presented. Differently shaped  TiO2nanocrystals  are  carefully  prepared  via  sol-gel  and  hydrothermal  synthesis  and  the influence  of  their  size  and  shape  on  the  photocatalytic  efficiency  of  hybrid  nanocomposites  was evaluated. The non-carbonized PANI/TiO2nanocomposites were synthesized by the chemical oxida-tive  polymerization  of  aniline  with  ammonium  peroxydisulfate,  in  the  presence  of  selected  TiO2nanocrystals,  while  the  carbonized  class  was  obtained  in the subsequent  carbonization  process, following  the  polymerization,  in  an  inert  atmosphere  at  650  °C.  The  morphology  and  structureof these nano-based photocatalysts was determined by TEM analysis and Raman spectroscopy. Func-tionality  of  nanocomposites  was  evaluated  following  the  photocatalytic  degradation  processes  of model compoundsMethylene blue and Rhodamine B and enhanced degradation efficiencies in the used dyes were observed

Ispostavlja se da napredni procesi oksidacije (engl. Advanced oxidation processes, AOPs) predstavljaju jedan od najefikasnijih procesa, među kojima heterogena fotokataliza, bazirana na upotrebi nanokristala TiO2 aktiviranih UV zračenjem, nesumnjivo predstavlja jedan od najčešće korišćenih tretmana za degradaciju organskih boja. Problem ograničene fotokatalitičke efikasnosti TiO2 pod dejstvom sunčevog zračenja može se prevazići formiranjem kompozita sa polianilinom (PANI), čija se uloga bazira na smanjenju rekombinativnih procesa e-/h+, kao i sposobnosti PANI-a da optički aktivira nanokristale TiO2, što je bila osnova za formiranje novih funkcionalnih PANI/TiO2 nanokompozita.

AB  - Differently-shaped TiO2 photo-nanocatalysts play a principal role in the remediation of environmental and pollution challenges considering their proven potential for treating organic contaminants in wastewaters [1]. However, increasing the photoactivity of TiO2 i.e. its optical response from UV into visible region is a constant challenge of many ongoing researchers [2]. An proceed towards this demand may be the creation of hybrid functional nanocomposites by coating the TiO2 nanocrystals (NCs) with electronically coupled conductive polymers (e.g., polyaniline (PANI), polypyrrole, etc.) [3]. By the carbonization process of mentioned conductive polymers at high temperatures, obtained final material possess carbon-like structure which impart additional properties [4]. Thus, the evolution of carbonized PANI (CPANI)- coated TiO2 NCs opens up the possibility for tailoring the photocatalyst with distinctive properties. This study implies development of new nanocomposites based on CPANI and colloidal TiO2 nanoparticles (NPs) (TPC) and CPANI and TiO2 nanotubes (NTs) (TTPC). Sol- gel and hydrothermal synthesis paths were used to obtain TiO2 NCs. The influence of their size and shape on the photocatalytic activity of formed carbonized nanocomposites was estimated. TPC and TTPC nanocomposites were synthesized according to the steps: 1) the non-carbonized PANI/TiO2 class was firstly prepared by the chemical oxidative polymerization of aniline with ammonium peroxydisulfate in the presence of TiO2 NPs or NTs and 2) the subsequent carbonization process was applied (650 °C). Developed hybrid nanocomposites were morphologically and structurally characterized by TEM measurements and Raman spectroscopy, while their functionality was estimated through the photocatalytic degradation processes of Methylene blue and Rhodamine B. All TPC and TTPC nanocomposites showed excellent photocatalytic properties, however, shape-depending of used TiO2 NCs.

AB  - A series of silver nanoparticles (AgNPs)-poly(vinyl alcohol)/poly(N-vinyl-2-pyrrolidone) (PVA/PVP) hydrogel nanocomposites were synthesized by gamma irradiation to examine the matrix's impact on properties of Ag nanocrystals important for strain engineering in functional materials. SEM analysis and the swelling studies revealed nanocomposite morphology and fluid transport properties. UV–Vis absorption characterization of AgNPs has enabled an understanding of the cluster size effects. The gel content indicated inter-crosslinking of the two components of the polymer matrix, especially for equivalent (1:1) PVA/PVP ratio, affecting the investigated AgNPs structural parameters. The lattice parameters and the interface stress, analyzed using XRD, have the lowest negative magnitude from the bulk lattice constant for the PVA/PVP (2:1) and (1:1) ratio. The lowest values of the lattice strain and dislocation density, as mutually dependent parameters, are obtained in AgNPs embedded in a PVA/PVP (2:1) and (1:1) matrix. The XPS and FTIR data show a positive shift of the O1s and a redshift of the CO – Ag vibration band indicating charge transfer to the vacant orbital of Ag nanocrystals. The N atoms of the pyrrolidine ring are not directly involved in the electronic interactions, but over the p-π conjugation with carbonyl O. In addition, the tested Ag-(PVA/PVP) hydrogel nanocomposites showed significant potential as a broad-spectrum antibacterial material.

AB  - In recent years, drug delivery systems have been one of the most investigated solutions for safer and more efficient therapy. Among many investigated materials, hydrogels with incorporated drugs and/or active substances can be produced in different ways to meet the criteria of biocompatibility, non-toxicity, continuous drug delivery, etc. In our previous work, the Ag- P(NiPAAm/IA) hydrogel nanocomposites were produced by radiolytic method, which enabled the synthesis and sterilization of materials in one technological step. Because of silver ions release, these hydrogel nanocomposites showed good antibacterial potential against both gram- positive and gram-negative bacteria. In this study, we go a step forward and investigate the silver release mechanism by fitting experimentally obtained data with several commonly used kinetics models of drug release.

abstract = "In recent years, drug delivery systems have been one of the most investigated solutions for safer and more efficient therapy. Among many investigated materials, hydrogels with incorporated drugs and/or active substances can be produced in different ways to meet the criteria of biocompatibility, non-toxicity, continuous drug delivery, etc. In our previous work, the Ag- P(NiPAAm/IA) hydrogel nanocomposites were produced by radiolytic method, which enabled the synthesis and sterilization of materials in one technological step. Because of silver ions release, these hydrogel nanocomposites showed good antibacterial potential against both gram- positive and gram-negative bacteria. In this study, we go a step forward and investigate the silver release mechanism by fitting experimentally obtained data with several commonly used kinetics models of drug release.",

AB  - Structural, conductive and dielectric properties of hybrid Polypyrrole (PPy)-TiO2 nanocomposite-coated polyamide fabric (PA-PPy/TiO2) synthesized by in-situ oxidative polymerization of pyrrole on the surface of polyamide in the presence of colloidal TiO2 NPs (d ~ 4.5 nm) have been studied. Raman spectra confirmed salt form of PPy in both neat PPy and PPy/TiO2-coated PA fabric and indicated its complete coverage. SEM/EDX analysis confirmed presence of TiO2 NPs and changes in granular structure of PPy deposited on the surface of PA fiber depending on the amount of TiO2 NPs. The PA-PPy/TiO2 nanocomposite sample with lowest content of TiO2 NPs (6.79 At.% Ti) showed highest conductivity (~10−6 S/cm) and dissipation factor (tan δ) in the entire frequency range. The lowest amount of TiO2 NPs in the PA-PPy/TiO2 nanocomposite induced two to four orders of magnitude higher tan δ value, compared to neat PPy covered PA fabric, depending on the frequency range. Frequency dependence of real (ϵ′) and imaginary part (ϵ″) of the complex permittivity for neat PA and PPy/TiO2-coated PA fabrics follow the trend of changes in dissipation factor for the same TiO2 NPs concentrations. The presence of TiO2 NPs could be exploited for tuning the conductive and dielectric properties of a conductive layer.

AB  - Hydrothermal synthesis of Mn2+ doped titanate nanotubes (TNTs), which exhibited room temperature ferromagnetism (RTFM), is reported. Dispersions of 1 and 5 at.% Mn2+ doped anatase TiO2 nanocrystals were used as precursors. Size and shape of Mn2+ doped TNTs and precursor nanocrystals were studied by transmission electron microscopy (TEM). The relatively uniform size distribution of transverse dimension of nanotubes of about 10 nm was observed while their lengths varied up to few hundred nanometers. The X-Ray Diffraction (XRD) analysis and Raman spectroscopy of resultant powder confirmed the hydrogen dititanate (H2Ti2O5 x H2O) crystal phase of Mn2+ doped TNTs with the presence of small amount of sodium titanates. Electron paramagnetic resonance (EPR) experiments were performed to probe the local atomic and electronic structure of Mn in the nanotubes. Room temperature ferromagnetic ordering with saturation magnetic moment (Ms) in the range of 0.6–1.5 μB per Mn atom was observed. © 2019 Elsevier Masson SAS

AB  - In a series researches so far, it has been shown that TiO2 nanoparticles have become the focus of intensive exploration in the field of photocatalysis, as a consequence of their unique properties and potential applications. In order to improve photocatalytic and functional properties of TiO2 nanoparticles, different methods should be used. One of the most effective approaches is capping of nobel metal (Pt, Ag, Au) clusters on nanoparticle surface. Namely, metal clusters act as electron traps and they promote interfacial charge- -transfer processes and reduce undesirable recombination processes on TiO2 nanoparticle surface.  As a consequence, photocatalytic efficiency of the system should be improved.  The cotton fabric modified by TiO2/Ag nanoparticles was synthesized by in situ photoreduction of Ag+-ions on alanine modified TiO2 colloidal nanoparticles previously deposited onto cotton fabric. Adsorption of Ag+-ions on TiO2 nanoparticle surface was improved by addition of alanine amino-acid. As a result, separation of photoinduced charges is preferred and recombination process is significantly reduced. In order to further improve the efficiency of the system, methyl alcohol was employed as hole-scavenger. Obtained results confirmed the presence of TiO2/Ag nanoparticles across the surface of cotton fabric (SEM), as well as successful fabrication of metallic Ag on investigated fabric (XRD). Interaction between alanine modified TiO2 and Ag nanoparticles was studied by FTIR, while structural properties of synthesized samples were investigated by Raman spectroscopy. The photocatalytic performance of TiO2/Ag nanoparticles modified cotton fabric was tested in the process of photodegradation of organic dyes under simulated solar light: Rhodamine B, Acid Orange 7 and Methyl Red.

AB  - This study discusses the possibility of in situ photoreduction of Ag+-ions on the surface of titania nanotubes (TNTs) deposited on the cotton and cotton/PET fabrics in the presence of amino acid alanine and methyl alcohol. TNTs were synthetized by hydrothermal method. The proposed interaction between titania, alanine and Ag+-ions was based on the results obtained by FTIR measurements. In order to enhance the binding efficiency between TNTs and fibers, the fabrics were previously impregnated with polyethyleneimine. The presence of TNT/Ag nanocrystals on the surface of fibers was proved by SEM, AAS, XRD and XPS. Larger amount of silver was detected on the cotton fabric. Fabricated TiO2/Ag nanocrystals provided maximum reduction of bacteria E. coli which was preserved after five washing cycles despite significant release of silver. The perspiration fastness tests indicated that silver release did not depend on pH. The presence of TNT/Ag nanocrystals imparted maximum UV protection to fabrics.

The presence of TNT/Ag nanocrystals on the surface of fibers was proved by SEM, AAS, XRD and XPS. Larger amount of silver was detected on the cotton fabric. Fabricated TiO2/Ag nanocrystals provided maximum reduction of bacteria E. coli which was preserved after five washing cycles despite significant release of silver. The perspiration fastness tests indicated that silver release did not depend on pH. The presence of TNT/Ag nanocrystals imparted maximum UV protection to fabrics.",

AB  - This study discusses the biodegradation behavior of cotton and cotton/PET fabrics impregnated with Ag/TiO2 nanoparticles in soil. Biodegradation behavior was evaluated by standard test method ASTM 5988-03 based on determination of percentage conversions of carbon content to CO2 as well as by soil burial test and enzymatic hydrolysis with cellulase where the extent of biodegradation was estimated by the calculation of fabric weight loss. The morphological and chemical changes of fibers during biodegradation process were analyzed by SEM and FTIR spectroscopy, respectively. The results obtained by all applied methods suggested that Ag/TiO2 nanoparticles hindered the biodegradation of investigated cotton and cotton/PET fabrics. Soil burial test indicated faster biodegradation of the impregnated blend compared to impregnated cotton fabric which is attributed to smaller amount of fabricated Ag nanoparticles on the blend proved by MS measurement. Similar trend was established by enzymatic hydrolysis of cotton fibers. Severe damage of cotton fibers in both fabrics due to biodegradation process was confirmed by SEM. However, the cotton fiber damage occurred to a lesser extent in the samples that were impregnated with Ag/TiO2 nanoparticles. PET fibers remained intact which was also indicated by FTIR analysis.

AB  - Polyester fibers gained significant share from all other man-made fibers, but despite numerous advantages a characteristic static electricity generation is still seeking innovative solutions. In order to improve electrical properties of poly(ethyleneterephthalate) (PET) fabric, coating consisting of polyaniline/TiO2 (PANI/TiO2) nanocomposite was deposited on its surface. Coating was synthesized in acidic medium by the chemical oxidative polymerization of aniline with ammonium peroxydisulfate CAPS) in the presence of colloidal TiO2 nanoparticles (d similar to 4.5 nm) and PET fabric. The morphology, molecular structure and dielectric properties of PANI/TiO2 nanocomposites were studied by scanning electron microscopy (SEM), Raman and dielectric spectroscopies. SEM analysis revealed the formation of non-uniform PANI coating on the reference PET sample. In contrast, uniform PANI/TiO2 coating on the surface of PET fabric was generated when TiO2 nanoparticles were engaged. The existence of conductive emeraldine salt form of PANI and phenazine units was confirmed by Raman spectroscopy. Formation mechanisms of PANI and PANI/TiO2 coatings on PET fabrics were proposed. The presence of TiO2 nanoparticles significantly affected the dielectric properties (permittivity and loss tangent) and AC conductivity of PANI/TiO2 coated PET fabrics. PET fabrics coated by PANI/TiO2 nanocomposite showed up to two orders of magnitude higher conductivity in the measured frequency region compared to PANI coated PET fabric. (C) 2015 Elsevier B.V.

AB  - The possibility of in situ photoreduction of Ag+ using colloidal TiO2 nanoparticles deposited on the surface of polyamide fabric in the presence of the amino acid alanine and methanol is discussed. The presence of TiO2/Ag nanoparticles on the polyamide fabric was confirmed by FESEM and ICP analyses. The antibacterial activity of the fabric was tested against the Gram-negative bacterium Escherichia coli and the Gram- positive bacterium Staphylococcus aureus. The TiO2/Ag nanoparticles fabricated on the surface of the polyamide fabric provided maximum bacterial reduction and thus, excellent antibacterial activity. In spite of silver leaching from the fabric during washing, the impregnated polyamide fabric preserved the maximum reduction of E. coli colonies. The antibacterial activity against S. aureus was slightly decreased after ten washing cycles, but still the antibacterial activity could be considered as satisfactory. In addition, the presence of TiO2/Ag nanoparticles ensured better UV protection efficiency, which belonged to the UV protection category very good.

AB  - The possibility of in situ photoreduction of Ag+-ions using TiO2 nanoparticles deposited on cotton and cotton/PET fabrics in the presence of amino acid alanine and methyl alcohol has been discussed. The possible interaction between TiO2, alanine and Ag+-ions was evaluated by FTIR analysis. The fabrication of TiO2/Ag nanoparticles on both fabrics was confirmed by SEM, EDX, XRD, XPS and AAS analyses. Cotton and cotton/PET fabrics impregnated with TiO2/Ag nanoparticles provided maximum reduction of Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus. Although excellent antibacterial activity was preserved after ten washing cycles, a significant amount of silver leached out from the fabrics into the washing bath. The perspiration fastness assessment revealed that smaller amounts of silver were also released from the fabrics into artificial sweat at pH 5.50 and 8.00. In addition, deposited TiO2/Ag nanoparticles imparted maximum UV protection to fabrics.
