The focus of the work Chris is undertaking for his PhD is on the development of carbon nanotube based electrodes for use within electrochemical sensors. Chris is mainly working on producing structured CNT forests, which can be used as the working electrode within a three-electrode system. He is controlling the structure, porosity and surface area of the CNT forest, as well as the functionalisation of the CNT surface to improve the design of the next generation of electrochemical sensors. Additionally Chris works on disposable paper based electrochemical sensors, again studying the affect structure has on the final sensing capabilities of the devices. Chris is a member of the Sensor Technologies and Applications CDT and a recipient of the Leete Premium award.
