Nano Gold Solution

Nanogold refers to gold atoms or molecules less than 50 nanometers in diameter. Compared with ordinary gold bullion or gold wire, the size of nanogold is very small, but its chemical composition and properties are the same as ordinary gold. Nanogold has important application value in many fields because of its small size and special physical properties. 
The side effect of nanogold makes it have unique physical and chemical properties. For example, the color and optical properties of gold nanoparticles change significantly with the decrease in size, with an obvious blue shift phenomenon. The large surface area of nanogold makes it have higher chemical reactivity and can catalyze chemical reactions more effectively. In addition, nanogold also has good electrical conductivity and electrochemical properties, which can be used to manufacture high-efficiency and sensitive electrodes and sensors.
