A REVIEW ON GOLD NANOPRTICLES SYNTHESIS AND CHARACTERIZATION

Gold nano particles (GNP) have exceptional biocompatibility and possess unique structural, electronic, magnetic, optical, catalytic and molecular recognition properties. Hence GNPs are very attractive for many biological applications. Being noble metal, the GNPs are resistant to oxide formation. Their electronic, magnetic and optical properties are size dependent. The optical properties of gold nano particles depend on nano particles size, shape, aggregation state, and local environment and are tuneable throughout the visible and near-infrared region. The current paper gives a brief review of different methods of synthesis of GNP with uniform size and shape and characterization of GNP by UV spectroscopy, dynamic light scattering, scanning electron microscopy and Fourier transform Infra Red spectroscopy along with applications of GNPs.
