Plant mediated synthesis of silver nanoparticles with diverse applications

Abstract

Green synthesis of multifunctional silver nanoparticles (SNPs) using leaf extracts of Simarauba glauca (Sg) and Artocarpus altilis (Aa), a good alternative to the electrochemical methods were exploited in this study for potential use as a biomedical agent in the medical field. Synthesis of SNPs using leaf extracts of Sg and Aa was carried out. The SNPs were characterized by UV-visible spectrophotometry, scanning electron microscopy, and Fourier transform - infrared spectroscopy analysis and evaluated for their multifunctionality. The SNPs were synthesized from the leaf extracts of Sg and Aa using silver nitrate with the reaction time of 2 minutes and 10 minutes, respectively. UV-visible absorption scan revealed a characteristic peak at 420 nm indicative of the surface plasmon resonance for SNP. The synthesized SNPs were of size ranges from 33 to 50 nm and 37.9 nm synthesized from the leaf extracts of Sg and Aa, respectively. Furthermore, the synthesized SNPs have shown excellent antibacterial activity against test pathogens, applicability in sewage water treatment, biofilm degradation and having perfect hemocompatibility. The biologically synthesized SNPs from the plant extracts could be of immense use in the medical field for their efficient antimicrobial function. The other valuable applications make it a potential agent in the relative biomedical area.
