Thesis Subject
Development of an Electrochemical Measurement at the Limits for Biosensor Applications
Previous work has demonstrated the potential of electrochemical measurement using high-frequency (GHz) techniques, achieving faradaic current resolutions on the order of attoamperes (10^-18 A) [1-3]. It has also been shown that measurement based on faradaic shot noise is possible [4]. The challenge now is to transfer these techniques to a chip-compatible measurement system using a coplanar waveguide architecture, assess their sensitivities, evaluate the possibilities of combining them, and test them with real biological samples—going beyond simple proof-of-concept demonstrations on electrochemical entities without biological function.
