WebGlucose can be extracted through intact skin by electro-osmotic flow (a process called 'reverse iontophoresis') upon the application of a low-level electrical current. Recently we have combined iontophoretic extraction with an in situ glucose sensor in a device called the GlucoWatch biographer. Web29 jan. 2024 · Iontophoresis is one of the physical permeation enhancers using an electric field . The repulsive forces between the same charge push the molecule into the skin; thus, iontophoresis promotes drug delivery with a low current density . Two mechanisms are possible to explain iontophoretic drug delivery: electro-osmosis and electro-phoresis.
