摘要：
Developing an economic and eco-friendly procedure for metallic nanoparticles synthesis is an important branch of nanobiotechnology. In the present study, biological synthesis of noble platinum nanoparticles and their characterization using neem extracts was investigated. The formations of nanoparticle dispersions were characterized by UV-visible spectrophotometer. TEM analysis showed the formation of nanoparticles in the range of 5-50 nm with polydisperse small sphere to large spheres. FT-IR measurement revealed that the protein is the possible biomolecule responsible for the reduction of chloroplatinic ion into platinum nanoparticles. The present study proved that medicinally valuable neem extracts have the capability to synthesize platinum nanoparticles and moreover, this green route makes it an easier, cost effective method.
