GRAPHENE OXIDE AND REDUCED GRAPHENE OXIDE

International Journal for Innovation Education and Research, 2021
To present a possible new alternative for wound treatment, this work evaluated the biological safety and therapeutic efficacy of graphene oxide (GO) and reduced graphene oxide (rGO) nanoparticles (NPs). First, the nanostructures were studied in silico and showed to be able to inhibit the production of some pro-inflammatory cytokines and stimulate the ...
