Investigating the best strategy to diminish the toxicity and enhance the antibacterial activity of graphene oxide by chitosan addition

The main objective of this work was to find a way to increase the bio-applicability of graphene oxide (GO) nanoparticles. In this way, various kinds of graphene oxide-chitosan (GO-CS) nano-hybrids were synthesized through attachment of different kinds of chitosan (CS) structures with GO. Subsequently, they were assessed in terms of structural characterization, antibacterial activity and cytotoxicity to obtain a hybrid structure representing the...
