Biosynthesis of copper nanoparticles; its characterization and efficacy against human pathogenic bacterium
Abstract Synthesis of nano material with the controlled size and shape is the prime concern of research in nanotechnology. Recently, biosynthesis of metallic nano particles has gained popularity owing to its eco friendliness. Use of natural plant extracts in the preparation of nano particles provides advancement over chemical and physical methods, due to its t is cost effectiveness and environment friendly nature. In the present work, copper nano particles have been synthesized with simple and green technique by using Ocimum sanctum plant leaf extract as reducer as well as stabilizer. The size and shape of synthesized nano particles were pigeonholed by particle size analyzer and SEM, further were characterized by EDS and FT IR spectral technique for their elemental and chemical composition. The experimental results showed copper nano particles having Z average diameter of 122.7 nm with higher stability and significantly higher antibacterial activities.
