Hi-Colloidal™ Gold Nanoparticles, 20 nm

Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. The field of Gold Nanoparticles applications is increasing day by day due to its strong adsorption, high biocompatibility and large surface area-to-volume ratio. Hi-ColloidalTM Gold Nanoparticles is extensively used for biomedical, diagnostics, therapeutics, sensors, probes and catalysis applications. The optical and electronic properties of gold nanoparticles are tunable by changing the size, shape, surface chemistry, or aggregation state.
