Evaluation of silver nanoparticles sorption activity on biogradable fibers of natural and artificial origin
The study established the features of the sorption activity of silver nanoparticles (AgNPs) on biodegradable polymers of natural (collagen) and artificial (polyamide 6.6) origin. The ability of naturally occurring absorbable fibers to more actively adsorb AgNPs ranging in size from 1 to 10 nm during the first hour and to retain them on the surface for the first day during exposure in argogel was demonstrated. When these polymers were incubated in a gel composition containing AgNPs obtained by cavitation-diffusion photochemical reduction, their higher sorption activity in the size range from 1 to 10 nm with respect to the multifilament synthetic material was revealed in the first hour, whereas after 24 hours of exposure was observed a significant increase in the fraction of small AgNPs already on collagen fibers, which was also accompanied by a significantly lower (19-fold) content on catgut AgNPs with a diameter of over 40 nm.
