Explore the world of biosensor technology in this inaugural lecture by Professor Danny O'Hare from Imperial College London. Delve into the development of minimally-invasive devices for diagnosing sepsis, managing chronic obstructive pulmonary disease, and monitoring therapeutic drugs. Gain insights into various aspects of biosensor development through real-world research examples, including cells-on-chips, the neurochemistry of ageing, and host-pathogen interactions. Discover how electrochemistry is used to measure molecules and its applications in cutting-edge medical diagnostics and research.
