AB  - In this work, the thermoelastic component of the photoacoustic response is derived, including the thermal memory of the material. The comparison between this model and the classic one, which does not account for the influence of thermal memory is made. It has been noticed that the two models tend to overlap at very high and very low frequencies of the light modulation spectrum, while in the middle range some deviations become more apparent, which proves that thermal memory must be taken into account. It has also been shown that the limits of this range are the function of heat propagation velocity and thickness of the sample. Based upon the processing of obtained data, it has been concluded that the characteristics of the output signal, in the range of the interest, are highly influenced by thermal dynamic qualities, like heat diffusivity and thermal relaxation time, as well as the sample thickness.

AB  - New hybrid hydrogels were prepared by radical copolymerization of 2-hydroxyethyl methacrylate, itaconic acid, poly(vinylpyrrolidone) and silver salt. FTIR spectroscopy has confirmed binding of silver particles in hydrogels. Swelling studies performed in in vitro conditions showed dependence on PVP content and temperature. It can be seen that the antimicrobial activity of the Ag/P(HEMA/IA)PVP hybrid hydrogels depends on the PVP moiety and with the increase of PVP content the microbial contamination is more efficiently reduced. The best sensitivity was obtained for the polymers tested for antimicrobial activity against the yeast C. albicans, one of the most commonly encountered human pathogens, causing a wide variety of infections ranging from mucosal infections in generally healthy persons to life-threatening systemic infections in individuals with impaired immunity. A slightly less susceptible to antimicrobial effect of hydrogels was obtained for the Gram-positive bacteria S. aureus, where the reduction of cells was about 70% after two hours of exposure, for the sample with the highest PVP content. The least susceptible to the antimicrobial activity of hydrogels examined was the Gram-negative bacteria E. coli, where the percent of cell reduction was below 20%. Bearing in mind the influence of the time of exposure of microbes to the Ag//P(HEMA/IA)/PVP hybrid hydrogels, it was observed that the reduction of the number of cells depends on time, microbial culture and type of hybrid hydrogel sample. Due to their swelling and antimicrobial properties, silver/poly(2-hydroxyethyl methacrylate/itaconic acid)/poly(vinylpyrrolidone) hybrid hydrogles show potential to use in the field of biomedicine, especially for treatment of skin and burns in dermocosmetics.

AB  - pH and temperature sensitive hydrogels, based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) copolymers, were prepared by gamma irradiation and characterized in order to examine their potential use in biomedical applications. The influence of comonomer ratio in these smart copolymers on their morphology, mechanical properties, biocompatibility and microbe penetration capability was investigated. The mechanical properties of copolymers were investigated using the dynamic mechanical analysis (DMA), while their morphology was examined by scanning electron microscopy (SEM). The morphology and mechanical properties of these hydrogels were found to be suitable for most requirements of biomedical applications. The in vitro study of P(HEMA/IA) biocompatibility showed no evidence of cell toxicity nor any considerable hemolytic activity. Furthermore, the microbe penetration test showed that neither Staphylococcus aureus nor Escherichia coli passed through the hydogel dressing; thus the P(HEMA/IA) dressing could be considered a good barrier against microbes. All results indicate that stimuli-responsive P(HEMA/IA) hydrogels have great potential for biomedical applications, especially for skin treatment and wound dressings.
