Nanotechnogy has played an important role in physical, chemical, biological and pharmaceutical sciences. The object consisted of the particles size 10-100 nm are usually known as nanomaterials. The important metal and metal oxide nanoparticles can be synthesised by using different physical and chemical methods. These methods are suffering with many disadvanges such as use of hazardous chemicals, low efficiency and high cost. Green synthesis of nanoparticles has been attracted for its efficiency, low cost and simplicity. In this study, silver nanoparticles (AgNPS) have been synthesised by using the extract of potato (Solanumtuberosum) tuber extract as reducing agent. The synthesised AgNPS were analysed by different analytical methods such as FTIR, powder XRD and FESEM. All these methods are indicating a sufficient formation of AgNPS. Biologically synthesised AgNPS have been tested for antibacterial activity. Remarkable zones of inhibition have been obtained for Streptococcus mutons, Proteus vulgaris and Escherichia coli.
