Green synthesis of silver nanoparticles using Hydnocarpus pentandra leaf extract: Evaluation of its antimicrobial and anti - Larvicidal activities

Nano Science and technology is an emerging area of research all over the globe because of the peculiar properties make it as a successful candidate in different cross cutting fields with multiple applications. The silver nanoparticles has much importance and widely employed in our day to day life as it exhibits immense potential antimicrobial activity against wide variety of pathogenic microorganisms and henceforth used commonly in medicines, organ implants, theatre products and pharmaceutical products. There are several traditional methodologies for the synthesis of nanoparticles, but all are expensive, time consuming, needs sophisticated equipment’s, chemicals and contaminate the environment. In the current work, we have approached the preparation of nanoparticles following green protocol with the leaf extract from a medicinal plant, Hydnocarpus pentandra. The silver nanoparticles prepared were characterized using UV-Vis Spectroscopy and Scanning Electron Microscopy. The antimicrobial activities where tested for gram negative (Escherichia coli) and gram-positive (Salmonella aureus) microorganisms. The method that we used here is simple, cheap, sustainable and non-poisonous to non-target organisms and does not cause any harm to environment. The larvicidal activity against mosquito larvae were assessed as per World Health Organization Standards. The nanoparticles synthesized exhibits excellent antimicrobial and anti larvicidal activities. We have come up with a novel technique for the synthesis of nanoparticles following green conduit, which is viable, simple, eco-friendly, cost effective, and have explored its applications in different fields.Nano Science and technology is an emerging area of research all over the globe because of the peculiar properties make it as a successful candidate in different cross cutting fields with multiple applications.
