Abstract

The discipline of nanotechnology is swiftly evolving as an interdisciplinary science, interfacing chemical, medical, environmental and physical sciences not leaving behind diverse engineering fields, with myriad of applications in the development of biosensors and biomedical devices, alternative energy generation and environmental restoration The principal objectives of this research work are Synthesis of silver nanoparticles from silver salts using biological route Characterization of these synthesized silver nanoparticles. Determination of the size and shape of silver nanoparticles study of its antimicrobial activity against a few common bacteria. In the rapid biological synthesis of silver nanoparticles using Diptheracanthus prostrates extract provides a stable, environmental extract provides a stable, environmental friendly, simple and efficient route for synthesis of nanoparticles. These obtained silver nanoparticles have potential applications in the biomedical field and this simple procedure has several advantages such as cost effectiveness compatility for medical and pharmaceutical applications as well as large scale commercial production. In the present study the extract was analyzed with help of UV, SEM and antimicrobial activity.

Keywords: Plant Extract, Silver Nanoparticles, UV, SEM and antimicrobial activity.
