MANUFACTURE, STUDY ANTIBACTERIAL ABILITY OF FABRICS UNIFORM WAS COATED COLLOID SILVER NANO

Abstract

   Silver nanoparticles which are highly effective in killing bacteria have been applied in many fields. One of its practical applications is that the silver nanoparticles are applied in textiles for creating antibacterial fabric.Nanoparticles of silver have been prepared by reduction of silver nitrate in ethylenglycol in the presence of polyvinylpyrrolidone with microwave heating. The UV - visible spectrum of the material shows a strong plasmon resonance band centered at 419 nm. The diameter of the silver particles defined by transmission electron microscopy showed that diameter is 6 - 10 nm. The cotton fabrics were immersed in nano silver colloid. The cytotoxic activities of the antibacterial cotton fabric have been evaluated for antiproliferative activity in vitro against. It was found that antibacterial activity increased with the increasing concentration of nano silver colloid.
