Enhanced analyte access through epithelial tissue
First Claim
1. A device comprising:
- an agent for enhancing a paracellular permeability of a device wearer'"'"'s epithelial tissue;
an iontophoresis electrode and a counter electrode, which are configured to increase the concentration of at least one analyte in a biofluid by the following;
using iontophoresis to transport the agent into the epithelial tissue, and using reverse iontophoresis to at least partially cause an advective flow of the biofluid from the epithelial tissue into the device; and
a collector for transporting the biofluid from the epithelial tissue into the device.

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.
