Abstract

In this project, we describe the development of ultrasensitive point-of-care electrochemical methods by incorporating nanostructured concentric electrodes - with vertically aligned single-walled carbon nanotubes - in microfluidic devices. The potential effect of this new assembly was evaluated using contactless conductivity detection (concentric electrodes) and voltammetric techniques (nanostructures electrodes).
