The present study aimed to prepare binary and ternary composites of nanochitosan (NCS), carboxymethyl cellulose (CMC) and graphene oxide (GO) for the biological and biomedical application. The prepared NCS/CMC, CMC/GO and NCS/CMC/GO composites were characterized using FTIR, XRD and SEM studies. The results revealed the suitability of the material for biological application with increased amorphous nature for cell adhesion. Antimicrobial studies were carried out against selected bacterial and fungal species. DPPH scavenging activity was done for the prepared biocomposites. NCS/CMC/GO ternary composite have the highest action against Bacillus sp (21 mm) followed by Klebsilla sp. (19 mm) and Proteus sp. (16 mm). For selected fungal species of Candida, Rhizopus and Aspergillus niger the ternary composites shows 28 mm, 26 mm and 24 mm inhibitory zone. The overall results exhibit the potential antioxidant and antimicrobial activity of the prepared composites.
