Description:Gold nanoparticles are a suspension consisting of nano sized gold suspended within a solvent, most often water. They have unique optical, electronic, and thermal properties and are used in a wide range of applications including diagnostics (lateral flow assays), microscopy and electronics. Nano-gold refers to the tiny particles of gold with a diameter of 1-100 nm. It has high electron density, dielectric properties and catalytic effect. It can be combined with various biological macromolecules without affecting its biological activity. Various colors of nano-gold have red to purple colors depending on the concentration. For nanoparticles material application, to disperse them well is usually a hard part for unexperienced users, offer nano Au colloidal / dispersion / liquid make it easier and more convenient for direct use.Storage Condition:Gold Nano (Au) Colloidal Dispersion should be stored in a cool dry place，the shelf life is six months.
