Silica Sulphuric Acid: An Efficient Reusable, Heterogeneous Acidic Media for Synthesis of Flavones (2-aryl-4H-chromen-4-one) by Cyclocondensation of o-hydroxyphenyl aryl-1, 3-propanediones”

摘要

Development of a biologically inspired experimental process for synthesis of nanoparticles is evolving into the area of nanotechnology research. Green synthesis of nanoparticles is very simple, non-toxic, cost effective and eco-friendly. The main aim of the investigation is to synthesize and characterize the silver nanoparticles using wound healing potent aqueous extract of raspberry leaf as a reducing agent and to evaluate their antibacterial activity. The formation of silver nanoparticles has been confirmed using UV–vis, XRD, SEM, EDX and FTIR analysis and its antibacterial activity was evaluated against Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. Silver nanoparticles showed a clear well defined inhibition zone compared to control plant extract. The results suggest the stabilized and reduced molecules of silver nanoparticles may act as an effective antibacterial agent for wound healing.
