Colloidal platinum

Colloidal platinum is a solution that comprises nano-size (1 nano-m is 1 billionth of 1 m, or, in other words, 1 millionth of 1 mm) colloid-shaped platinum particles. This substance supplies electrons to and eliminates elements such as reactive oxygen and radicals, and, since platinum is resistant to oxidation, is said to be able maintain this function semi-permanently.
