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.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
