Abstract

Dispersions of metal nanoparticles were obtained at the gas discharge treatment of aqueous solutions of CuCl2, CuSO4 and AgNO3. Direct current discharge was excited between a metal cathode located in the air and metal salt solution being used as an anode at a current of 5–25 mA. The average sizes of obtained nanoparticles were estimated using dynamic light scattering method. The sizes have been shown to depend on the solution concentration, discharge current and processing time. The obtained nanoparticles were applied from dispersions to medical dressings and their bactericidal activity was tasted. Samples treated with silver-containing particles showed bactericidal activity against bacteria Escherichia coli, Staphylococcus albus, Bacillus subtilis and microscopic fungus Candida albicans. Copper-containing samples did not show biological activity.
