ABSTRACT: The present and fast-growing demands of the synthesis of nanoparticles with various areas suchas medicine and energy, catalysis, electronics and chemistry increased day to day. In the pastdecade, nanoparticles are prepared from wet chemical method, where chemicals used are quietflammable and often toxic. In this report, we are going to synthesize gold nanowires from bacterium Pseudomonas aeruginosa. Gold nanowires were synthesized through the reduction of aqueous Au3+ ion using the growth culture supernatants. Gold nanowires were formed within 1 h of gold ion coming in contact with the cell filtrate. The synthesized gold nanowires were characterized from TEM, UV-Vis and DLS.An absorption peak at 550 nm in Uv–Vis spectrophotometer was detected indicating the presence of gold nanowires. The DLS analysis showed gold nanowires with size of 90±15 nm.
