The aqueous sol of gold nanoparticles is "gold standard" :) for a lot of studies. "Non-stabilized" (but stable) colloidal gold in water could be synthesized chemically (for example, reduction of chloroaurate by hydrogen peroxide), but preferably physically (laser ablation method, exploding wire method, etc).

Gold Nanoparticles of different sizes like 10nm, 20nm, 40nm can be made. They remain disperesed in water for a couple of weeks.
