Biological activity prospects of selenium-decorated graphene oxide composite by green synthesis using Sesbania sesban flower extract

Abstract

In this work, the nanostructured composite of selenium and graphene oxide was synthesized using Sesbania sesban extract. Accordingly, the results showed a successful fabrication of the material, which involved the contribution of the phyto-compounds in the extract and graphene oxide as reducing and stabilizing agents. Moreover, the appearances of both nanoparticles and nanorods on the graphene oxide nanosheets were also observed without the occurrence of any interference. By applying the material to various microorganisms, the results were fruitful and provided insightful speculation. Specifically, both the antibacterial and antifungal activities revealed high performances, and the relative inhibition mechanism was generally discussed. Finally, the antioxidant and anti-inflammatory effects of the material were also assessed. In general, the results suggest the potential of the material as the smart alternative role in medical and pharmaceutical aspects.
