Abstract
In this work, beetroot extract is used to synthesize the silver-iron oxide (Ag-Fe2O3) bimetallic nanoparticles, which are then characterized and used for the antioxidant studies. Phenolic components were found to coat the nanoparticles, according to FT-IR analysis. Tannins and flavonoids in the extract serve as stabilizing and reducing agents. SEM revealed spherical bimetallic nanoparticles that were roughly 40 nm in size. Crystallinity and purity were shown by XRD examination, which also revealed unique reflection peaks. Particle size and zeta potential values clearly confirm that, the prepared bimetallic nanoparticles are in nano size and it is stable in nature. Furthermore, in this study, the antioxidant properties of produced bimetallic nanoparticles are examined, and their efficacy is compared to that of beetroot extract. Beetroot extract-silver-iron oxide (BE-Ag-Fe2O3) bimetallic nanoparticles showed improved radical scavenging effectiveness when compared to DPPH. Moreover, bimetallic nanoparticles demonstrated increased radical scavenging efficacy in relation to DPPH and H2O2. Surprisingly, at 20 mg/ml, the BE-Ag-Fe2O3) bimetallic nanoparticles showed good scavenging activity, reaching 84.65%. The produced bimetallic NPs had greater antioxidant activity than the plant extract, according to an analysis of the total antioxidant capacity and free radical scavenging activity data. Electron donation property of main constituent of beetroot extract was analysed by density functional theory (DFT) and Monte Carlo (MC) simulation. Consequently, this work implies that beetroot extract assisted bimetallic NPs could be a flexible material with a range of uses in the biomedical area.Graphical
