• The optical and electronic properties of gold nanoparticles vary by changing the size, shape, surface chemistry, or aggregation state.
• Gold nanoparticles can be used as conductors from printable inks to electronic chips. As the world of electronics are becoming smaller and smaller, gold nanoparticles are important components in chip design. Nanoscale gold nanoparticles are being used to connect electronic components such as resistors, conductors, and other elements of an electronic chip.
• Gold nanoparticles are used as catalysts in various numbers of chemical reactions. The surface of a gold nanoparticle can be used for selective oxidation or in certain cases the surface can reduce a reaction (for example, to nitrogen oxides).
• In addition, Gold nanoparticles are being developed for fuel cell applications. These technologies of gold nanoparticles would be useful in the automotive and display industry.
• Gold nanoparticles are also used in detection of biomarkers in the diagnosis of heart diseases, cancers, and infectious agents.
