Gold Nanopowder

Gold Nanopowder Applications

Gold nanopowder refers to a fine, powdery form of gold that consists of nanoparticles of gold. Nanoparticles are tiny particles with dimensions typically in the nanometer scale, which is on the order of 1 to 100 nanometers. Gold nanopowder is often produced through various chemical and physical methods, including chemical reduction of gold salts, sol-gel processes, and laser ablation.
