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.
Claims16
A composition of matter comprising a colloidally stable suspension of naked metal nanocrystals having an average particle size of no more than 100 nm.
A method of making a colloidally stable suspension of naked metal nanocrystals comprising the steps of:
- a. at least partly immersing a metallic sacrificial anode and a cathode into a body of essentially contaminant-free water, said metallic sacrificial anode comprising an essentially contaminant-free metal starting material for making nanocrystals;
- and
- b. applying a voltage potential across said anode and said cathode to form a colloidally stable suspension of naked metal nanocrystals consisting essentially of metal from said metallic sacrificial anode.
