Eco-Friendly Synthesis of Iron Oxide Nanoparticles using Abrus Precatorius Seed and Evaluation of their Antibacterial and Antioxidant Activities

Abstract

The current study uses Abrus precatorius (AP) seed to synthesize iron oxide nanoparticles (AP-FeONPs) in a green way. Utilizing SEM, XRD, IR, and UV-DRS, the generated nanoparticles were characterized. Using the DPPH assay, the antioxidant activity of AP-FeONPs was evaluated using ascorbic acid as the standard and determined their IC50 values as 22.40 µg/ml (AP-FeONPs) and 10.3112 µg/ml (ascorbic acid). The bio fabricated iron oxide nanoparticles (APFeONPs) demonstrated strong antioxidant activity in comparison to ordinary vitamin C. The antibacterial properties of AP-FeONPs were assessed against Bacillus subtilis and Escherichia coli at concentrations as high as 100μl. The results showed that, at high concentrations of 100μl, AP-FeONPs possesses significant bacterial inhibition against Bacillus Subtilis and Escherichia coli.
