An Eco-friendly Approach for Nanosilver Synthesis and its Therapeutic Aspects

Abstract

Nanosciences along with the emergence of nanobiotechnolgy and nanomedicine in the last few decades provided a number of opportunities for exploring the bactericidal and fungicidal activities of metal nanoparticles. In the present scenario silver in the form of nanoparticles are playing a major role in the field of Nanotechnology and Nano medicine, their unique size dependent properties make them superior and indispensable. Silver nanoparticles are particles in the size ranging between 1 and 100 nm. Although nanoparticles can be synthesized through array of conventional methods, biological route of synthesizing are good competent over the physical and chemical techniques. Green principle route of synthesizing have emerged as alternative to overcome the limitation of conventional methods among which plant and microorganisms are majorly exploited. Employing plants towards synthesis of nanoparticles are emerging as advantageous compared to microbes with the presence of  broad variability of bio-molecules in plants can act as capping and reducing agents and thus increases the rate of reduction and stabilization. In addition, the biological synthesis of metallic nanoparticles is inexpensive, single step and eco-friendly methods. Nanosilver has developed as a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent and also in diagnostic and therapeutic applications. The aim of this review is to provide an overview of recent trends in synthesizing nanoparticles via biological entities and their potential applications.
