Graphene Oxide-Silver Nanocomposite as a Promising Biocidal Agent Against Methicillin-resistant Staphylococcus aureus
In this study, published in the International Journal of Nanomedicine, November 2015, researchers concluded that silver nanoparticles “exhibited an excellent antibacterial activity against Methicillin-Resistant S. aureus (MRSA), Acinetobacter baumannii, Enterococcus faecalis, and Escherichia coli.”
The researchers state that 100% of the MRSA cells were inactivated after 4 hours of exposure to the silver nanoparticles which were embedded in a graphite oxide matrix. “In addition,” the researchers stated, “no toxicity was found within the tested concentration range” for either the graphite oxide or the silver nanoparticles. The researchers concluded, “Our results indicate that the graphite oxide silver nanocomposite is a promising antibacterial agent against common nosocomial bacteria, particularly antibiotic-resistant MRSA.”
