Synthesis of Sodium Alginate Graphene Oxide-Silver Film for Antibacterial Activity

Abstract

A facile preparation of graphene oxide silver alginate film (GO-Ag) has been constructed for the antibacterial activity. Graphene oxide (GO) was used as a substrate towards arranging of unagglomerated silver nanoparticle (AgNPs) by a simple microwave irradiation on combination of GO and silver complexes in the presence of alginate. The obtained nanocomposite were characterized by using Ultraviolet-visible spectroscopy (UV-Vis) and Xray Diffraction to confirm the formation of film composite. AgNPs with spherical-shape deposited on the GO Alginate layer which displayed a good antibacterial towards E.Coli and Staphylococcus aureus.
