Developing an electrochemical sensor using in-situ synthesis of a stand-alone MIP membrane for bacteria detection in water

In this project, a microfluidic sensor will be developed for bacteria detection in water. The microfluidic device enables in-situ synthesis of molecularly imprinted polymer (MIP) membranes with bacteria imprinted cavities. The
sensor works based on bounding the target bacteria to the MIP membrane, thereby altering the electrochemical signal which will be measured using in-situ fabricated electrodes. In the short term of the Mitacs internship, the
characterization of the MIP membrane will be completed, electrodes will be fabricated and their electrochemical stability towards oxidation at different electrolyte concentrations will be tested. Then, the sensor’s sensitivity
towards different concentrations of bacteria will be quantified. Finally, the sensor’s dose-response curve will be constructed. The sensor can be integrated with portable fluid handling, and electrochemical measuring systems
for point-of-need water quality monitoring.
