Synergic bactericidal effects of reduced graphene oxide and silver nanoparticles against Gram-positive and Gram-negative bacteria

Reduced graphene oxide (rGO) is a promising antibacterial material, the efficacy of which can be further enhanced by the addition of silver nanoparticles (nAg). In this study, the mechanisms of antibacterial activity of rGO–nAg nanocomposite against several important human pathogenic multidrug resistant bacteria, namely Gram-positive coccal Staphylococcus aureus and Gram-negative rodshaped Escherichia coli and Proteus mirabilis are investigated.
