Biomimetic synthesis of iron oxide nanoparticles using Canthium coromandelicum leaf extract and its antibacterial and catalytic degradation of Janus green

The present study was emphasized to investigate the novel use of aqueous leaf extract of Canthium coromandelicum (CC) to synthesize iron oxide nanoparticles (CC-IONPs) by reducing Iron(II) chloride. FT-IR analysis revealed that the presence of polyphenols and organic acids in CC extract, which was responsible for capping and stabilization of CC-IONPs. SEM image confirmed the spherical nature, and EDS spectrum confirmed the presence of iron peak at 6.3 keV. In addition, magnetic nature with a saturation magnetization of 20.32 emu/g was observed using vibration sample magnetometer (VSM). The biogenic synthesized CC-IONPs exhibits potential antibacterial activity against Staphylococcus aureus and Salmonella typhi. Furthermore, CC-IONPs exhibited tremendous degradation efficiency (97.23%) for Janus green B (JG) at 180 min under sunlight irradiation.
