Abstract

An automated system for continual transdermal extraction of analytes present in a biological system is provided. The system can be used for detecting and/or measuring the concentration of the analyte using an electrochemical biosensor detection means.
The system optionally uses reverse iontophoresis to carry out the continual transdermal extraction of the analytes.
