Abstract
The invention relates to a device and method for non-invasive detection of an analyte in a fluid sample. In one embodiment, the device comprises: a collection chamber containing an absorbent hydrogel material; a fluidic channel connected to the collection chamber; a sensing chamber connected to the fluidic channel, wherein the device is comprised of a compressible housing that allows transfer of fluid collected by the collection chamber to be transferred to be extracted and withdrawn to the sensing chamber upon compression of the device, wherein the sensing chamber contains a material that specifically detects the analyte and wherein the sensing chamber is operably linked to a processor containing a potentiostat that allows detection of the analyte using electrochemical sensing.
