Abstract
Infections caused by microorganisms possess a great global public health problem which demands advanced antimicrobial strategies. Now-a-days, nano metallic 2D antibacterial materials have gained enormous interest for the development of antimicrobial biomaterials research owing to long service life and fast effective bactericidal speed. In the present work, we have utilized the active energy of graphene, and its visible band plasmonic hotspots tunability of gold nanoparticles embedded graphene along with NIR active Fe2O3 to synthesize G@GNP-Fe3O4 active sheets having bactericidal properties in a broad spectrum of VIS to NIR. The synthesized materials showed antibacterial action in visible white light, outdoor sunlight, and NIR light with no killing action in dark environment.
