Fabrication, Characterization, Antibacterial and Biocompatibility Studies of Graphene Oxide Loaded Alginate Chitosan Scaffolds for Potential Biomedical Applications

Abstract

Graphene oxide nanomaterial possesses greater biocompatibility. Chitosan alginate is produced from chitin by deacetylation, it is a biodegradable and biocompatible biomaterial. Graphene has a large specific surface area that enhances the antibacterial effect by enabling biocompatible interactions with bacterial membranes. To fabricate a biocompatible graphene oxide loaded alginate chitosan scaffold for potential biomedical uses and perform the characterization, antibacterial, and biocompatibility properties of ALG-CHI-GO scaffolds. The scaffolds were prepared by mixing the solution of ChitosanHCl (5 %) and graphene oxide-oxidized alginate (10 %). This gelled mixture is freeze-dried (lyophilization) to form the scaffold and is later characterized using FTIR and SEM, The scaffolds were then tested for in biocompatibility towards peripheral blood mononuclear cells and antibacterial properties against Enterococcus faecalis and Streptococcus mutans. The biocompatibility towards peripheral blood mononuclear was checked using the annexin V PI assay. To conclude that the fabricated Graphene oxide loaded chitosan alginate scaffold was found to be biocompatible and showed antibacterial properties.
