Obtaining silver bactericidal layers on surface of porous matrixes from anodic alumina by chemical deposition

Abstract

Silver films due to such properties as high electrical and thermal conductivity, high corrosion resistance and antibacterial properties are now widely used in biomedical technique and biotechnology. At present work was investigated the processes of chemical deposition of silver nanoparticles into a porous matrix of anodic aluminum oxide with nanosize pores. According to the results obtained, the process of chemical deposition of silver particles on porous anodic alumina with preliminary impregnation of Sn (II) ions was proposed. The extended surface of the obtained nanocomposite film provides high bactericidal effect and can be used for water disinfection.
