Multiple valence silver nanoparticles with irregular shape were anchored on reduced graphene oxide sheets by light irradiation. The characterization analysis revealed silver nanoparticles with different valences were uniformly attached on the surface of reduced graphene oxide sheets and mostly in the size of 30nm. The antibacterial activities of the as-obtained nanocomposite against gram-negative bacteria E. coli and gram-positive bacteria S. aureus were investigated. Moreover, stability of the nanocomposite was measured by silver ion release. It was found that the nanocomposite has enhanced antibacterial activity and outstanding stability, which makes it a potential antibacterial agent.
