Abstract

An apparatus for sensing an analyte is described, wherein the apparatus includes an interface contact element that is used to establish an interface with a quantity of body fluid. The interface contact element is adapted to facilitate diffusion of a target analyte across the interface essentially free of net mass fluid transport. The quantity of body fluid is exposed to the interface contact element through micro-pathways. The apparatus can also include a sensing material adapted to sense the target analyte with at least one analytical method. Methods for using the apparatus in a non- or minimally invasive monitoring technique are also described.
