Abstract

In this paper, properties and applications of gold nanoparticles have been discussed. Gold nanoparticles exhibit outstanding optical properties. These properties show variations with size of gold nanoparticles and their surface features. Gold spheres with dimension greater than 20 nm exhibit purple color. They exhibit red color for 10-20 nm size and appears yellow at 2-5 nm dimension. Gold nanoparticles show single electron tunnelling which describes their excellent conductivity. Gold is non magnetic in bulk size but at nano dimension it shows magnetic behaviour due to change in magnetic coupling. Due to all these outstanding properties, gold nanoparticles have been utilized for various applications like biological tagging, biomedical imaging, catalysis, cancer therapy, food packaging and monitoring, scatterind based imaging, biosensors, sunscreen, drug delivery, DNA labelling etc.
