In recent years, environmental friendly synthesis approaches and the use of benign reaction precursors are becoming more and more popular in chemistry, chemical technologies and the need for ecological methods of synthesis is increasing to minimize or even eliminate the use of hazardous chemicals. In this concern, “green” processes have been adopted for the benign synthesis approaches that use less reaction conditions and non-hazardous reaction precursors. Another important advantage of green synthesis methods lies in its cost-effectiveness and in the abundance of raw materials. Application of green chemistry to the synthesis and characterization of nanomaterials has vital importance in medicinal and technological aspects. Synthesis of silver nanoparticles is of much interest to the scientific community because of its unique properties and wide range of applications. The present study deals with the synthesis of silver nanoparticles using aqueous extract of Ridge Gourd (Luffa acutangula) peel as the reducing agent to study the antimicrobial activity. The formation of Ag-NPs was confirmed by Scanning Electron Microscopy (SEM) equipped with Energy Dispersive X-Ray Spectroscopy (EDS), Fourier Transform-Infra Red Spectroscopy (FT-IR), X-Ray Diffraction (XRD) pattern. The FT-IR analysis reveals that the synthesized Ag nanoparticles were capped by the polyphenolic compounds present in the peel extract. The antimicrobial activity of these nanoparticles was studied against Staphylococcus aureus, E.coli, Pseudomonas aeruginosa, Proteus vulgaris. The present study indicated that Ag-NPs have considerable antimicrobial activity in comparison with standard antimicrobial drug.
