The paper studies the interaction between surgical catgut and silver nanoparticles depending on the fiber surface treatment and time of exposure (1 and 24 hours) in Ag-containing gels. After a 24-hour exposure, the maximum sorption capacity is observed on polished catgut for silver nanoparticles ranging in size from 1 to 10 nm. After this time period, the sorption capacity of silver nanoparticles on unpolished catgut occurs in Agcontaining gel within the whole size range, mainly from 1 to 5 nm, when silver nanoparticles are obtained by cavitation and diffusion photoreduction. At the same time, the incubation period of 1 hour in Argogel does not provide the potentially effective concentration of silver nanoparticles on the fiber surface. Keywords: silver nanoparticles, plain surgical catgut, electron microscopy, sorption.
