Nanotechnology is the modern research field which deals with design, synthesis and manipulation of particles structure range from 1-100nm in dimension. A nanoparticle is ultra-fine unit with dimension less than 100 nm (1 nm=10-9 meter).Because of their small size they have unique characteristics and their applications in various field such as medicines, engineering and environmental remediation. Nanoparticles can be prepared by various aapproaches like physical, chemical and biological .The biological approach is the emerging approach because it is easier than other methods. In this green synthesis aqueous solution of extract of Azadirathcha indica and AgNo3 were taken for study. The nanoparticles were prepared by using plant extract and silver metal ions. The nanoparticles were characterized by different spectral methods like UV, IR, DLS, SEM, XRD and Zeta analysis.
