Micro- and Nano-electrodes for Electrochemical Sensing in Biomedical Applications

Abstract

Reducing electrode dimensions enhances characteristics and performance in electrochemical sensing. A multi-disciplinary collaborative team at the University of Edinburgh has developed a range of micro- and nano-scale electrode systems that can be fabricated on silicon wafers using industry standard fabrication techniques offering the potential to economically produce large arrays of identical electrodes. This platform offers “More than Moore” capabilities, often leading to a more complete solution in the system integration and translation phases. The seminar will cover the technology, current capability, some applications with emphasis on oxygen sensing in clinical applications, and future potential.

About the speaker

Following a bachelor’s in Natural Philosophy, master’s in Bioengineering, and doctorate in Applied Optics, Prof. Ian UNDERWOOD was appointed lecturer in Electronics at the University of Edinburgh (UoE), pioneering the field of liquid crystal on silicon (LCoS). A Fulbright Fellowship at the University of Colorado introduced him to technology entrepreneurship, co-developing Boulder Nonlinear Systems’ first product to a Photonics Spectra Circle of Excellence Award.

He supported the formation of Micropix Technologies (now Kopin) then founded MicroEmissive Displays where he worked for ten years. Awards include Emerging Entrepreneur of the Year, Gannochy Award for Innovation of the Royal Society of Edinburgh, Top European semiconductor start-up and IEE Award for Emerging Technology. His favourite is “smallest tv screen in the world” – a Guinness World Record. He provided advice to the Scottish Government as a member of the Scottish Science Advisory Council, 2008-12.

Returning to UoE Prof. Underwood added miniature sensor technologies to his research portfolio in a range of applications from biomedical to astrobiology. He continues to support technology start-ups including Holoxica, Optoscribe, Sofant, BrightPage, and was founding Chair of PureLIFI. He has a growing interest in structured, thematic, cohort-based, multi-disciplinary doctoral training and is Director of the Advanced Care Research Centre’s innovative PhD Academy.

Prof Underwood was elected a Fellow of the Royal Society of Edinburgh, 2005; Royal Academy of Engineering (RAEng), 2008; Institute of Physics, 2008; and Society for Information Display, 2022. He is Publications Chair at the Society for Information Display and a mentor in the Enterprise Hub at the RAEng.
