The unique structure of silver nanoparticle–graphene (AgNP–GE) nanocomposites gives them excellent antimicrobial properties. First, the sheetlike AgNP–GE nanocomposites are adsorbed and accumulated on the surface of cells through electrostatic attraction, which changes the permeability and enhances the antimicrobial activity. Second, Ag+ ions released from AgNPs act on the cells effectively and fully, thereby resulting in cell death.
