Polymer-Stabilized Nanosilver Complexes Doped with Fullerene: Stability in Salt and Oxidizing Media, Antifungal Properties

Composites based on silver nanoparticles (AgNPs) and fullerene C60 were obtained. AgNPs were stabilized by alternating copolymers of maleic acid. The properties of the composites were studied by UV-Vis spectroscopy, dynamic light scattering (DLS), and X-ray photoelectron spectroscopy (XPS). The contents of AgNPs and C60 in the composites were 22–34 wt % and 20–28 wt %, respectively. The dry composites were found to be dispersible in water. It was shown that the stability of AgNPs in salt- and oxidant-containing media increases upon their doping with fullerene C60. Moreover, C60 significantly enhances the antifungal activity of AgNPs in the composites against Candida albicans.
