Abstract
Nano-biotechnology is an undoubtedly future generation technology which offers potential applications in multidisciplinary areas of science and technology. In the present day’s production, stabilization and utilization of nanoparticles is the eliminatory division in modern science receiving immense attention of scientists engaged in different fields of research. A number of metal nanoparticles have been engineered so far; however among these, silver nanoparticles gain more attention because of their unique applications in distinctive fields of biology. This review presents an overview on phytosynthesis of silver nanoparticles; role of phytochemical constituents in reduction of silver nanoparticles, factors responsible for the synthesis of silver nanoparticles and their crucial role in control of size and shape etc. The biological applications of phyto-synthesized silver nanoparticles are given in brief which will direct a path for further biological studies in future to make the study more useful for human welfare and benefits. Key words: Phytosynthesis, silver nanoparticles, phytochemicals, biological activities.

Antimicrobial assay of biosynthesized among these silver nanoparticles (AgNPs) against both Gram-negative (E. coli) and positive (S. aureus) microorganisms at different concentrations was studied (Singhal et al, 2011) and they revealed a strong dosedependent antimicrobial activity against both the tested microorganisms
Recent research works regarding the photo-biological approach for the synthesis of silver nanoparticles were summarized in the present review
