PhD Project by Nicolai Støvring

Project Title: Pyrolytic Carbon Nanogap Electrodes for Bioelectrochemistry
Group: Biomaterial Microsystems
Supervisor: Stephan Sylvest Keller

Project Description
At present, most electrochemical sensor platforms are based on rather macroscopic electrode geometries. It has been shown that micro- and nanoelectrode platforms with very small spacing between working and counter electrode allow for redox cycling and significant amplification of the signal in electrochemical sensing. The amplification factor (AF) is even further enhanced with the use of 3D electrodes with higher surface areas.

In this project, different schemes for fabricating pyrolytic carbon micro- and nanogap electrodes will be tested and employed for achieving high AF. Furthermore, finite element simulation will be used in the design phase of the electrodes. To facilitate the electrochemical characterization of the electrodes, a 3D printed parallel testing platform will also be fabricated. The full system will be employed to monitor cyanobacteria.
