Abstract
A method of making a colloidally stable suspension of naked metal nanocrystals includes the steps of: at least partly immersing a metallic sacrificial anode and a cathode into a body of essentially contaminant-free water, the metallic sacrificial anode that includes an essentially contaminant-free metal starting material for making nanocrystals; and applying a voltage potential across the anode and the cathode to form a colloidally stable suspension of naked metal nanocrystals composed essentially of metal from the metallic sacrificial anode.
