Preparation of NanoSilver coated Cotton Fabric and its bactericidal evaluation

Abstract

We have developed silver nanoparticle coated cotton fabric and evaluated its anti bacterial efficacy. Silver nanoparticles were synthesized by chemical reduction of silver nitrate using hydrazine hydrate as reducing agent and polyvinyl alcohol as stabilizing agent. It is coated over cotton cloth by ultrasonication method. The anti-microbial efficacy has been studied by inhibition zone assay and agar plate count assay against gram negative bacteria. The longevity of anti-bacterial property of clothes has also been determined by checking its bactericidal effect after washing the cloth several times by Ezee brand liquid soap.
