Abstract
In the recent period, nanomaterial with enhanced multifunctional activity and less mammalian toxicity were greatly required. With this perception, the stability, cytotoxicity and antimicrobial, photocatalytic traits of Amaranthus spinosus leaf extract (B-FeO NPs) and sodium borohydride (C-FeO NPs) abridged iron oxide nanoparticles were studied. The analysis results confirmed that B-FeO NPs have better physicochemical characters than C-FeO NPs. The NPs cytotoxicity were tested against MCF-7 cells by MTT assay. The results confirmed that B-FeO NPs cytotoxicity was lesser than C-FeO NPs. The antibacterial and antibiofilm activity of both NPs were tested using Escherichia coli and Bacillus cereus. The outcomes depicted that synthesized NPs have good inclination against E. coli than B. cereus bacteria. The photocatalytic efficiency of NPs was assessed using degradation of naphthalene. The result indicate maximum degradation efficiency of 97% for 40 ppm naphthalene under UV light. These results suggest that B-FeO NPs have better physicochemical traits; also, it can be used as an effective bio-catalytic material in biological Industry.
