Introduction
Three noble metals, also called precious metals, are currently used in medicine: gold, silver, and platinum. None of these metals are considered essential, and there are no daily requirements. Nanocolloids are the metallic form of these metals finely divided with particle sizes below 10 nanometers (nm). One nanometer is one billionth of a meter. As a general rule, the ionic forms of these metals display more toxic reactions than the metallic form of these metals. The metallic form acquires new physical, chemical, and physiological properties when finely divided with particle sizes in the low nanometer range. Only the ionic, most toxic forms of these ...
