Abstract
Transdermal analyte monitoring systems (TAMS) having increased longevity and improved analyte detection are described herein. Kits for use with the TAMS and methods of using the TAMS and kits are also described. In a preferred embodiment, the TAMS includes a protective, semi-permeable membrane covering the surface of the hydrogel. The protective, semi-permeable membrane contacts with the skin of a user and prevents contamination or fouling of the hydrogel. Optionally, the hydrogel comprises one or more humectants and/or an immobilized enzyme. In another preferred embodiment, the TAMS contains at least one channel or pocket for increasing the amount of oxygen provided to the hydrogel. In one embodiment, a method for improving analyte detection by the TAMS is provided. For example, after the skin porosity is increased by an appropriate pretreatment, a skin preparation wipe is applied to the treated skin area and then the TAMS is applied to the treated area.
