A technological scheme of the process of electron beam evaporation and condensation for synthesis of PVP–Ag nanocomposites is considered. The influence of output mass of silver, beam current, time and rate of silver evaporation on the size of silver nanoparticles is evaluated. The TEM method and photon-correlation spectroscopy were used to study the structure of PVP-Ag composite and PVP–Ag–H₂ O and PVP–Ag–alcohol colloid systems. Methodological and experimental developments of medicinal substances with antimicrobial activity based on Ag nanoparticles are considered. The studied substances were glucosamine with nanosilver, PVP with nanosilver and low-toxic gels with silver nanoparticles. A test sample with a pronounced bactericidal action against gram-positive (S.aureus) and gram-negative (р.аеruginosa) microorganisms was studied. [ABSTRACT FROM AUTHOR]
