Green Synthesis and characterization of nanoparticles is under exploration due to its wide medical applications and various research interests in nanotechnology. In the current study, the plant extract of Persea Americana (Avocado)(Family-Lauraceae) is used for the synthesis of silver nanoparticles (AgNPs). This study investigates an efficient and sustainable route of AgNPs preparation from 1 mM aqueous AgNO3 using leaf extracts. The complete reduction of silver ions was observed after 12 hrs of reaction at 40°C under shaking condition. The colour changes in reaction mixture (pale yellow to dark brown colour) was observed during the incubation period, because of the formation of silver nanoparticles (AgNPs) in the reaction mixture enables to produce particular colour due to their specific properties (Surface Plasmon Resonance). The formation of silver nanoparticles was confirmed by UV-Visible spectroscopy, Fourier Transform Infra-Red (FT-IR) spectroscopy analysis, X-Ray Diffraction (XRD) pattern, Transmission electron microscopy (TEM). The results showed that the leaf extract is optimum for the synthesis of silver nanoparticles and it is also known to have the ability to inhibit the growth of various pathogenic microorganisms. The average size of synthesized silver nanoparticles is found to be 27.42 nm using XRD data by Scherrer’s formula, which is approximately similar as the size obtained in TEM Analysis (27.58nm). In total, the AgNPs prepared are safe to be discharged in the environment and possibly utilized in processes of pollution remediation. AgNPs may also be efficiently utilized in Anti-inflammatory activity of Pharmaceutical research to obtain better result of plant as shown by our study. © 2015, Global Research Online.
