Iontophoresis is a physical process in which ions flow diffusively in a medium driven by an applied electric field.ontophoresis of acetylcholine is used in research as a way to test the health of the endothelium by stimulating endothelium-dependent generation of nitric oxide and subsequent microvascular vasodilation.
