About the Seminar:

Carbon has become a popular material for electrochemical sensors due to its wide availability, low cost, and excellent electrochemical properties. More importantly, carbon electrodes can take on several different forms, from robust thermoplastic electrodes to flexible stencil-printed electrodes. This allows carbon-based electrodes to be used in variety of different applications and environments such as pathogen detection. For pathogen detection, a key component of analysis is quantification of the target analyte. An electrochemical approach allows for quantitative response, rather than a qualitative one, enabling the end user to determine elements such as infectivity or quantity. This talk will focus on the development of electrochemical immunosensors using carbon-based electrodes for both SARS-CoV-2 and Escherichia coli (E. coli). Broadly, discussion will focus on the successful development of a SARS-CoV-2 assay, and its performance against clinical samples, variants, and interferents. Preliminary assay development and the obstacles associated with such will be detailed for the detection of E. coli.
