Enhanced analyte access through epithelial tissue

Abstract

A device for increasing a concentration of at least one analyte in an advective flow of biofluid includes an agent for enhancing a paracellular permeability of an epithelial tissue; and an iontophoresis electrode and a counter electrode, which are adapted to increase the concentration of said analyte in the advective flow of the biofluid. A method of sensing an analyte in a biofluid includes increasing a paracellular permeability of an epithelial tissue layer; and inducing electro-osmotic flow by reverse iontophoresis to increase a concentration of said analyte in an advective flow of the biofluid, wherein said advective flow is driven by at least one of saliva generation, sweat generation, or reverse iontophoresis.
