Abstract
Nanomaterials including graphene and its derivatives have attained immense popularity among scientific community due to their unique properties. Graphene (G), graphene oxide (GO), reduced graphene oxide (rGO) and their nano-composites have shown to possess enormous potential in the field of nanomedicines. Graphene family nanomaterials (GFNs) have extensively being used in different fields including antibacterial formulations. Mechanisms underlying the toxicity of GFNs involve the interaction of sharp edges of graphene derivatives with the bacterial cell wall, charge transfer and formation of huge number of reactive oxygen species. The use of graphene derivatives including GO-Ag nanocomposites, polydopamine-graphene nanosheets, rGO-Iron oxide NPs, Pluronic-GO, G-Carbon Nanotubes-iron oxides, Ag-rGO-Fe3O4-polyethylenimine composites, ZnO-GO and Cystamine-GO has revealed a strong antibacterial action against a variety of bacteria. In this paper, an attempt has been made to comprise the latest approaches being put forward in various researches based on the antibacterial action of graphene based nanomaterials and their composites
