ADSORPTION OF SILVER NANOPARTICLES ON MONO- AND POLYFILAMENT FIBERS

Resumo

Abstract—The study evaluated the adsorption of Ag-containing solutions and gel compositions on modern natural and artificial fibers, as well as polyfilament threads with different coatings. It was determined that natural fibers are characterized by the highest adsorption. The developed gel composition based on silver nanoparticles also demonstrates high sorption on suture thread material combined with a chemically inert coating (e.g., silicone). The distribution of silver nanoparticles on Polyester suture thread material was accompanied by a significant predominance (up to 76%) of particles 1 to 5 nm in size. It has been established that silver nanoparticles as part of the Argogel preparation can be efficiently adsorbed by various suture thread materials, primarily when exposed to Sabfil (up to 36%) and Dexon (up to 38%) threads. After 1 h of exposure to a synthesized Ag gel with silver nanoparticles obtained by cavitation-diffusion photochemical reduction, the nanoparticles are significantly (up to 14%) sorbed on the surface of the suture thread material, including Catgut and Dexon, with decreased subsequent aggregation of sorbed nanoparticles. It was determined that although the components of the suture thread material do not deactivate silver ions, it remains highly probable that they will bind to various ions, primarily forming insoluble silver chlorides and phosphates in the wound fluid.
