Nanotechnology is the study and application of small object which can be used across all fields such as chemistry, biology, physics, material science and engineering. In the present work, the experiments were conducted for the biosynthesis of Silver nanoparticles by using fruit extract of Ichnocarpus frutescens (L.) W. T. Aiton . This was taken to investigate their potential for antimicrobial activity. UV-Vis absorption spectroscopy is one of the main tools to analyze the formation of metal nanoparticles in aqueous solution. The FTIR analysis was carried out to identify the possible interfacial groups between the capping agents and silver nanoparticles. The AFM was used to analyze topography of nanoparticles and also to measure their size. The test plant mediated biogenic silver nanoparticles shows spherical Ag-NPs which range from 5 to 50 nm. Antimicrobial analysis data reveals that S. aureus, E. coli, B. subtilis, B. polymyxa and S. typhi microbes showed maximum zone of Inhibition. These are sensitive with suppressed growth rate; it is due to toxic effect of biogenic AgNPs synthesized by selected test plant species.
