Surface| Zusammenfassung: | Nanobiocomposites based on ultrafine silica, titania/silica (containing TiO2=20%) and protein of bovine serum albumin were obtained, showing various range of bioactivity with respect to deconservated bovine gametes. Method of adsorption of protein from aqueous phase at рН 4,8 was used for obtained of nanobiocomposites. Isotherms of adsorption were obtained and parameters of the process were calculated. Bioactivity was estimated by parameters of cell motion using laser Doppler spectroscopy. Its dependence upon the nature of on nanooxide surface and their concentration were established. It was noted nanobiocomposites demonstrate lower ability of aggregation in cell-containing media in comparison with initial nanooxides. |
