Green synthesis of silver nanoparticles using Garlic extract and evaluation of antibacterial activity

simple, environmentally friendly and cost-effective method has been developed to synthesize silver. nanoparticles (AgNPs) using Garlic extract.The AgNPs were synthesized using silver nitrate and garlic extract, and the reaction was carried out for 2 h at room temperature Antibacterial activities of synthesized silver nanoparticles were evaluated against four bacteria, E.coli, S. aureus, B. subtilis and P. aeruginosa. The results revealed that silver nanoparticles show good antibacterial activities. Also, we characterize the synthesized nanoparticles with with X-ray diffraction (XRD) ), Scanning electron microscopy (SEM) and UV/Visible absorption spectrophotometry. The absorption peak was found in the region of 422 nm. These nanoparticles would contain an average mean diameter of 24.42 nm by Scherrer equation
