AB  - The laser desorption/ionization time-of-flight (LDITOF) mass spectra of the
solution of Gd2O3 in HCl are reported. The results presented here illustrate
the usefulness of the linear positive mode of LDI in the characterization of
gadolinium metal ions. In addition, the laser desorption/ionization also leads
to the formation of several ionic species containing gadolinium with oxygen
and chlorine, which were detected in the negative linear mode. The ion
signals are identified by both m/z values and distinctive isotope patterns.

AB  - The aim of this study is to evaluate the size and stability of radiolytically produced silver clusters. The clusters obtained by the gamma irradiation of a mixture of a silver salt and polyvinyl alcohol (PVA) were studied both theoretically and by mass spectrometry. MALDI TOF mass spectrometry of the Ag-n clusters showed the presence of clusters containing between 5 and 29 atoms. Both the theoretical and experimental results of this paper show that the most stable clusters are small clusters with an odd number of atoms. The stability of these clusters is correlated with the clusters electronic configuration. (C) 2012 Elsevier Ltd. All rights reserved.

AB  - A primer is a strand of nucleic acid that serves as a starting point for DNA
synthesis. DNA, as a large molecule, is very difficult for analysis by means of mass
spectrometry. However, primer, as a short sequence of nucleic acid, is much more
convinient for e.g. MALDI TOF MS analysis. Mass spectrometric experiment
resulted in quality MALDI TOF spectra of 3 primers. Compound 3-HPA (3-
hydroxypicolinic acid) showed the best results as matrix. AFM studies were also
conducted, for both pure primer samples and hybrids of primer molecule with
single wall carbon nanotubes (SWNT). Thus, obtained functionalisation of SWNT
with DNA primers was confirmed by AFM imaging. AFM images clearly showed
wrapping of DNA structures around nanotube „template“. Functionalisation of
SWNT is very important for potential applications of nanotubes in biomedical
field. MALDI TOF mass spectrometry, in combination with AFM imaging, proved
its great potential in analysis of short DNA sequences, and indicated the possibility
of investigating more complex DNA structures.

AB  - Collagens, one of the most abundant on the Earth, are family of proteins which constitute the basis of connective tissue (extracellular matrix) in multicellular organisms. We used collagen type II from bovine Achilles tendon. In further work, collagen has been studied by transmission electron microscopy (TEM) and atomic force microscopy (AFM). Using TEM we successfully obtained images of collagen and whole collagen fibrils. Using AFM we captured images of whole collagen as well as images of fragments from collagenase-treated collagen (it was digested with collagenase from Clostridium histolycium). AFM images of collagenase-treated collagen showed many fibrils grouping into large bundles – collagen fiber. Based on obtained images we studied surface morphology, shape and length of fragments from collagenase-treated collagen.

AB  - Bone is composed of two phases. The organic phase is made of collagen fibrils assembled in broad fibers acting as a template for mineralization. The mineral phase comprises hydroxyapatite (HAP) crystals grown between and inside the collagen fibers. We have developed a material using functionalized carbon nanotubes, carbon fibers and glasy carbon as scaffold to initiate in vitro mineralization. Mentioned carbon materials are functionalized with carboxylic groups prior to decorating. All samples were dispersed in ultra-pure water and incubated for 2 weeks in a synthetic body fluid with dispersed HAP, in order to induce the calcification of the functionalized carbon materials. Atomic force microscopy (AFM) and transmision electron microscopy (TEM) showed that Ca2+ and PO4 3- ions were deposited as round-shaped nodules. Raman spectroscopic studies confirmed the HAP formation, and image analysis made on TEM pictures showed that HAP were packed around and inside the carbon materials together. All three types of investigated carbon materials leading to successful calcification of collagen. This suggests that it takes the presence of carbon materials to prevent it from calcification of collagen, independent of the structures of the material.

AB  - In this study we performed the dynamic and static scintigraphy of the domestic dog, using the newly synthesized radiopharmaceutical, [Tc-99m(CO)(3)(H2O)(3)]-C-60(OH)(22-24). In the current study, an advanced one-step method for the functionalization of fullerenol by Tc-99m is described. Optical properties of as-prepared samples and the mechanism responsible for the functionalization were investigated using UV-VIS and FTIR spectroscopy, respectively. Also, the presence of the Tc complex on fullerenol was confirmed by using the energy dispersive X-ray spectroscopy, HPLC and MALDI TOF techniques. This simple and effective method of producing a new radiopharmaceutical is of interest not only for its application in various areas of technology and biology, but also for investigating its potential use in radiation technology for nanoengineering of materials. With dynamic scintigraphy, performed during 30 minutes (120 frames, 15 sec per frame), we obtained ratios of heart, liver and spleen counts: 222/249/168; 178/320/217; 120/348/239 respectively. By static scintigraphy after 1 hour, we detected the activity in heart, liver, spleen and intestines. After 4 hours, the radiopharmaceutical activity was detected in salivary glands. The detection after 21 hours showed the activity in kidneys and urinary bladder, while the activity in intestines was absent. After 24 hours, we detected the activity in liver, spleen, kidneys and urinary bladder. Pharmacokinetic investigations performed in this study are of key interest for the further fullerenol in vivo research.

AB  - In this study, we analysed pellets from long-eared owls (Asio otus) collected from four localities in Belgrade (Serbia). The pellets contained the remains of prey, namely voles (Arvicola terrestris) and field mice (Apodemus agrarius). The concentrations of 14 elements (Ca, P, Mg, Na, K, Fe, Zn, Sr, Ba, Mn, Ti, Cu, Si, B) were evaluated in whole pellets and in samples containing only bone tissue, which were dissected from the whole pellet. The increased levels of certain elements, including Mn, Zn, Ba, Cu and radioactive K-40, indicate contamination of the soil by various sources, such as industrial plants and agricultural practices. From the results presented in this article, we suggest that the analysis of owl pellets may indicate the quality of the local environment.

AB  - In this paper, an advanced method of one-step functionalization of single and multi walled carbon nanotubes (SWCNTs and MWCNTs) using gamma-irradiation was described. Two synthesis procedures, related with different reduction species, were employed. For the first time, poly(vinyl alcohol) PVA is successfully utilized as a source to reduce silver (Ag) metal ions without having any additional reducing agents to obtain Ag nanoparticles on CNTs. The decoration of carbon nanotubes with Ag nanoparticles takes place through anchoring of (PVA) on nanotubes surface. Optical properties of as-prepared samples and mechanism responsible for the functionalization of carbon nanotubes were investigated using UV-vis and FTIR spectroscopy, respectively. Decorated carbon nanotubes were visualized using microscopic techniques: transmission electron microscopy and scanning tunneling microscopy. Also, the presence of Ag on the nanotubes was confirmed using energy dispersive X-ray spectroscopy. This simple and effective method of making a carbon nanotube type of composites is of interest not only for an application in various areas of technology and biology, but for investigation of the potential of radiation technology for nanoengineering of materials.

AB  - Silver clusters were produced by two different synthesis procedures, related with
different reduction species. PVA (polyvinyl alcohol) was successfully utilized as a
source to reduce silver (Ag) metal ions without using any additional reducing
agents to obtain Ag clusters. Silver clusters with atoms numbering 5-29 are
registered through mass spectrometry using MALDI TOF and MALDI TOF/TOF
techniques. Analysis showed that clusters with magic numbers are the largest,
while those with an odd number of atoms are larger than clusters with an even
number of atoms. Stability of these molecules, magic number actually, is in
relation with their electronic configuration.

AB  - Carbon nanotubes are unique one-dimensional macromolecules with promising applications in biology and medicine. Since their toxicity is still under debate, here we present a study investigating the genotoxic properties of purified single wall carbon nanotubes (SWCNTs), multiwall carbon nanotubes (MWCNTs), and amide functionalized purified SWCNTs on cultured human lymphocytes employing cytokinesis block micronucleus assay and enumeration of gamma H2AX foci as a measure of double strand breaks (DSBs) of the DNA in normal human fibroblasts. SWCNTs induce micronuclei (MN) formation in lymphocytes and decrease the proliferation potential (CBPI) of cells. In a fibroblast cell line the same dose of SWCNTs induces gamma H2AX foci 2.7-fold higher than in a control. Amide functionalized purified SWCNTs behave differently: they do not disturb the cell proliferation potential of harvested lymphocytes, but induce micronuclei to a higher extent than SWCNTs. When applied on fibroblasts, amide functionalized SWCNTs also induce gamma H2AX foci, 3.18-fold higher than the control. The cellular effects of MWCNTs display the broad spectrum of clastogenic properties seen as the highest incidence of induced lymphocyte micronuclei and anaphase bridges among nuclei in binucleated cells. Surprisingly, the incidence of induced gamma H2AX foci was not as high as was expected by the micronucleus test, which indicates that MWCNTs act as clastogen and aneugen agents simultaneously. Biological endpoints investigated in this study indicate a close relationship between the electrochemical properties of carbon nanotubes and observed genotoxicity.

AB  - Using the ion implantation technique (introducing negatively charged fullerene into a low temperature lithium plasma column by a strong axial magnetic field) endohedral fullerenes Li"C-70, Li-2"C-70 and Li-3"C-70 were produced. Mass spectral studies (both TIMS-thermal ionization mass spectrometry and MALDI TOF MS - matrix assisted laser desorption ionization time-of-flight mass spectrometry) of these endohedral fullerenes provided detailed structural and reactivity information about these unusual species. The fragmentation of the obtained ions is shown to be by a multiple C-2 loss (shrink-wrap mechanism). According to the fact that more atoms in the fullerene make the produced endohedral less stable, Li-3"C-70 shows a big degree of instability. The presence of Li-3"C-70 was observed on MALDI TOF MS.

abstract = "Using the ion implantation technique (introducing negatively charged fullerene into a low temperature lithium plasma column by a strong axial magnetic field) endohedral fullerenes Li"C-70, Li-2"C-70 and Li-3"C-70 were produced. Mass spectral studies (both TIMS-thermal ionization mass spectrometry and MALDI TOF MS - matrix assisted laser desorption ionization time-of-flight mass spectrometry) of these endohedral fullerenes provided detailed structural and reactivity information about these unusual species. The fragmentation of the obtained ions is shown to be by a multiple C-2 loss (shrink-wrap mechanism). According to the fact that more atoms in the fullerene make the produced endohedral less stable, Li-3"C-70 shows a big degree of instability. The presence of Li-3"C-70 was observed on MALDI TOF MS.",

The ionization energy of Li6F5 cluster was obtained experimentally for the first time. The ionization energies of Li3F2 and Li4F3 are in correlation with the results obtained by photoionization time-of-flight mass spectrometry. The determined ionization energies are comparable with theoretical ionization energies calculated by ab initio method.

AB  - In this work we have studied the Li/C-60, Li/C-70, (99)mTc/C-60, (TC)-T-99/C-70, Gd/C-60, Gd/C-70, Nd/C-60, Nd/C-70, Y/C-60 and Y/C-70 systems by surface ionization mass spectrometry and investigated a possibility of the formation of endohedral fullerenes. Using the ion implantation technique (introducing negatively charged fullerene into a low temperature lithium, technetium, gadolinium, neodymium or yttrium plasma column by a strong axial magnetic field), the endohedral fullerenes Li congruent to C-60, Li congruent to C-70, Li-2 congruent to C-70, Tc-99m congruent to C-60, Tc-99m congruent to C-70, Gd congruent to C-60, Nd congruent to C-60, Y congruent to C-60, Gd congruent to C-70, Nd congruent to C-70 and Y congruent to C-70 have been produced and ionization energies were measured. Their existence was demonstrated through the high sensitivity, magnetic mass spectrometer (TIMS- thermal ionization mass spectrometer). These metallofullerenes were identified as stable molecules. The reaction of the obtained endohedral fullerenes with oxygen compounds (H2O, O-2 and N2O) has also been investigated. The result showed that these metallofullerenes are very inert to all of these gas phase oxygen-rich molecules, leading support to the endohedral structure of the metallofullerenes. Observed ionization energies for Li congruent to C-60, Li congruent to C-70, Li-2 congruent to C-70, Tc-99m congruent to C-60, Tc-99m congruent to C-70, Gd congruent to C-60, Nd congruent to C-60, Y congruent to C-60, Gd congruent to C-70, Nd congruent to C-70 and Y congruent to C-70 were 5.9eV, 5.1eV, 5.3eV, 5.1eV, 5.3ev, 6.2eV, 6.5eV, 6.6eV, 6.4eV, 6.5eV and 6.7eV, respectively.

AB  - Mass spectral studies (both TIMS – thermal ionization and MALDI TOF – matrixassisted laser desorption time-of-flight mass spectrometry) of the endohedral metallofullerenes, 99mTc@C60 and 99mTc@C70, provided detailed structural and reactivity information about these unusual species. MS experiment revealed that both fullerenes and endohedral metallofullerenes fragment by multiple C2 loss. However, a difference in the terminal fragmentation products was observed for metallofullerene relative to C60, suggesting that the encapsulation metal strongly impacts the fragmentation product. Singly charged cations of the metallofullerenes (M@Cn + ) were completely unreactive in the gas phase with oxygenated compounds such as ethylene oxide: however, the corresponding neutral species appear to react readily with oxygenated species. Collisional dissociation of the ionized endohedral fullerenes listed above revealed multiple C2 loss (either as sequential C2 loss or larger C2n eliminations) to generate similar terminal fragmentation products, which might be predicted due to the similar ionic radii of the encapsulated metals. The observed ionization energies of endohedral molecules were, 5.1 ± 0.1 eV and 5.3 ± 0.1 eV, respectively.

Collisional dissociation of the ionized endohedral fullerenes listed above revealed multiple C2 loss (either as sequential C2 loss or larger C2n eliminations) to generate similar terminal fragmentation products, which might be predicted due to the similar ionic radii of the encapsulated metals. The observed ionization energies of endohedral molecules were, 5.1 ± 0.1 eV and 5.3 ± 0.1 eV, respectively.",
