Metallic nanoparticles are widely employed in every phase of science, engineering and medical field. Also several studies have proven their antimicrobial significance. Synthesis of metallic nanoparticles is still charming arena to scientists for exploring novel dimensions for their respective worth which is generally attributed to their corresponding small sizes. Conventionally nanoparticles are synthesized using chemicals as reducing agents by chemical method which pose to various environmental risks due to their general harmfulness. It engenders the serious concern to develop environmentally friendly processes. Hence, biological approaches are shown quite interest to fill the void; for green syntheses of nanoparticles using biological molecules derived from plant sources in the form of extracts. In the present study, rapid, simple approach has been applied for synthesis of silver and silver doped zinc nanoparticles using aqueous Anamirta cocculus leaf extract. The plant based biological molecules of Anamirta cocculus undergo highly controlled assembly for making them suitable for the metal nanoparticle syntheses. Various techniques were carried out to characterize synthesized nanoparticles such as FTIR, UV, SEM, and EDX. Investigation on antifungal activity showed that the nanoparticles exhibit good potential antifungal activity against Apergillus flavus and Apergillus terreus. Results confirmed this protocol as simple, nontoxic, rapid and eco-friendly an alternative conventional chemical methods.
