Product Name
Name：Au Nanoparticles
Product Overview
Gold nanoparticles can also be referred to as nano gold colloids, which are a colloidal system formed by dispersing nano gold particles in a solution. The commonly used preparation methods for nano gold colloids include sodium citrate reduction chloroauric acid method, also known as seed growth method, electrochemical synthesis method, etc. The color of nano gold colloids changes with the size of gold nanoparticles. Generally speaking, the larger the diameter of gold nanoparticles, the longer the wavelength of light absorbed by their solution shifts towards longer wavelengths, and the particles will exhibit complementary colors to the absorbed light.
