Abstract
Nanoparticles shows improved characteristics because their size, morphology and distribution, and are extensively used in various scientific fields. Among metallic nanoparticles, Silver Nanoparticles (AgNPs) are very significant particularly because of their physicochemical and antimicrobial properties which help in molecular diagnostics, therapies and devices used for medical processes. A major adverse effect of chemical synthesis is that it involves the use of hazardous chemicals and toxic by-products are obtained. Thus, there is a requirement for eco-friendly and economic methods to synthesize them and the utilization of aqueous or alcoholic plant extract are quickly expanding and gaining significance. Various plant extracts are used for the green synthesis of AgNPs, one among them is Hypericum perforatum. Hypericum perforatum aqueous extract was used for the synthesis of AgNPs and its antifungal action was proved. This article explains about their main physical chemical properties of synthesized AgNPs and some of their medical applications.
