Characterization and Antibacterial Properties of Eriobotrya Japonica Extract Loaded Silver-Nanoparticles

Abstract

Background: Currently, developing methods for the formation of nanoparticles with antimicrobial properties based on green chemistry are the research hotspots. In this research, green biosynthesis of Eriobotrya japonica extract loaded silver nanoparticles and their characterization were the main objectives to achieve. Methods: Green synthesis of E. japonica leaves extract-loaded silver nanoparticles (AgNPs) was carried out and its effect on bacterial growth was examined. The reduction of silver ions in the solution was observed using a UV-Vis spectrophotometer. The properties of AgNPs were assessed using Scanning Electron Microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and Xray Diffraction (XRD). Also, their antibacterial effects were checked against Staphylococcus aureus and Escherichia coli. Results: It was revealed that 5-50 nm sized spherical to elongated nanoparticles were synthesized that possessed comparatively better antibacterial potential against E. coli and S. aureus than the conventional extract of the E. japonica leaves. Conclusions: Green synthesis and effective utilization of Eriobotrya japonica extract loaded silver nanoparticles are a promising approach for nanoparticle production avoiding negative environmental impacts.
