Nature Meets Nanoscience: Comparison Between Plant Mediated Green Synthesis of Copper and Iron Nanoparticles from Embelia Ribes and Peltophorum Pterocarpum and Their Biological Applications

ABSTRACT The present research investigates the microwave‐assisted synthesis of copper and iron nanoparticles which offers emerging strategies for development of eco‐friendly and sustainable approaches leading to the environmentally responsible biomedical applications. This green chemistry approach was meant for the comparative study of the synthesized Copper and Iron nanoparticles from Embelia ribes and Peltophorum pterocarpum extracts. UV‐visible spectroscopy, FT‐IR, TEM, XRD and Zeta potential were used to characterize the synthesized Cu and FeNPs. The synthesized nanoparticles exhibited UV‐Visible spectrum between 200‐400 nm and FT‐IR was done for the determination of functional groups. By utilizing TEM particle size were observed ranging from 10 to 50 nm. The XRD data depicted sharp and crystalline peaks and the stability studies showed zeta potential values at −12.43 and −11.93 mV. The comparative study of the synthesized nanoparticles showed that the CuNPs mediated by E. ribes exhibited significant zone of inhibition against bacterial pathogens for antibacterial and antifungal activity. The DPPH radical scavenging assay showed higher antioxidant capacity in FeNPs derived from P. Pterocarpum than CuNPs mediated by E. ribes , emphasizing the environmentally responsible, economical and sustainable ways to create Cu and Fe nanoparticles for use in medical applications.
