Gold Colloid

naggregated and monodisperse with narrow size distributions Dispersible in the desired solvent Available at high concentrations Posesses a well defined surface (sometimes referred to as a capping agent) Long shelf life and stable in a variety of conditions Highly purified with low concentrations of residual chemicals from the manufacturing process.

Gold colloid is a suspension consisting of sub-micron gold nanoparticles suspended within a solvent, most often water. Gold nanoparticles have unique optical, electronic, and thermal properties and are being incorporated in a wide variety of technologies including microscopy, electronics, diagnostics, and therapeutics.
There are many important criteria that must be considered when selecting gold colloid for us in any of these technologies. In all cases, a desirable material will have the following characteristics.
