This work demonstrates the use of a new Ag-NPs synthesized from reduction method of silver nitrate, for efficient ability and activity against various pathogenic bacteria. Here, this research is done in with the purpose of synthesizing silver nanoparticles while studying its antimicrobial properties on Gram positive and Gram negative bacteria. Sodium borohydride has been used for the reduction and capping of silver nanoparticles. The reduction process of Ag+ to Ag0 was observed by the change of color from clear yellow to cloudy gray. In addition, the synthesized of Ag-NPs followed by the characterization of the silver nanoparticles using UV-Vis, XRD pattern and CFU have been calculated. Antimicrobial activity of Ag-NPs was done by well diffusion method against pathogenic organism like Salmonella typhi. Finally, the optimum temperature has also determined which was 40°C. This work confirms that Ag-NPs have the antimicrobial efficacy.
