ABSTRACT
It is shown that injection of silver nanoparticles (NPs) into large-tonnage polymers, such as polystyrene (PS) and styrene copolymer with acrylonitrile (SAN), imparts fungicide properties to them. For the purpose of further forecasting, the process of microscopic fungi and bacteria growth in the presence of different silver NP concentrations has been described quantitatively. It is shown that addition of silver NPs significantly suppresses growth of Aspergillus niger and Penicillium chrysogenum microscopic fungi both at the initial, and stationary stages of their growth. Inhibition of bacterial growth manifests itself in increased induction period (the lag-phase).
