Abstract

Specific features of the synthesis of stable silver nanoparticles by chemical reduction with agents differing in the reducing ability were studied using spectrophotometry, photon correlation spectroscopy, and scanning electron microscopy methods. The antimicrobial activity of the silver-containing sols synthesized was evaluated in tests with clinical strains (Staphylococcus aureus and Escherichia coli), and its dependence on the reduction conditions and, accordingly, on the size of the resultant particles was revealed. The synthesized sols of silver nanoparticles with sizes below 50 nm proved efficient in protecting cellulosic textile materials against attacks by natural complex of microflora and by soil microflora.
