WebGold nanoparticles are commonly produced in a liquid by reducing chloroauric acid. After dissolving the acid, the solution is rapidly mixed along with a reducing agent. This process then causes Au 3+ ions to be reduced to neutral gold atoms. As more of these gold atoms are generated, the solution becomes supersaturated.
