Gold nanoparticle 
Catalog Number GNS-10281
Description The product is also known as nanogold colloid, which is a colloidal system formed by gold nanoparticles dispersed in solution. The commonly used methods for the preparation of gold nanocolloid are sodium citrate reduction method, electrochemical synthesis method and so on. The color of gold nanocolloid changes with the size of gold nanoparticles. In general, the larger the diameter of the gold nanoparticles, the more the wavelength of the light absorbed by its solution moves in the direction of the long wave, and the particles will show the complementary color of the light absorbed.
