Nano Gold Powder Liquid Au nanoparticles Aqueous Colloidal Solution
Gold nanoparticles, the particle size of 20 nm - 1 um all can be customized production, the purity of 99.99%, and can make into dispersion. Gold nanoparticles aqueous solution, using gold nanoparticles dispersed in water, forming stable homogeneous solution, the color is wine red, change with the concentration. Gold nanoparticles aqueous solution has the following features: 1. Appearance: wine red liquid. 2. The particle size of 20 nm, adjustable 3. Non-toxic tasteless safe and reliable. 4. The concentration can be adjusted according to the requirements. 5. Efficient catalysis, removing free radicals effect, antibacterial antioxidant ability. Why Hongwu Nano supply nano Au dispersion: for easier application.
