Biography: 

Alan Murray is Professor of Neural Electronics and Assistant Principal, Academic Support. He introduced the Pulse Stream method for analogue neural VLSI in 1985. Alan’s interests are now primarily in implanted silicon chips for biomedical applications.

He led the £5.2M IMPACT (Implantable Microsystems for Personalised And-Cancer Treatment) project, funded by an EPSRC Programme Grant and enjoys teaching first year engineering/electronics and third year Electromagnetics courses. IMPACT produced proof-of-concept results that will be taken forward in two areas – cancer and wound-healing, as "OPTIMIST" (Optimised, Personalised Treatment & Intervention: Microsystems, Implanted Sensors & Therapeutics).

Alan is a Fellow of IET, IEEE and the Royal Society of Edinburgh, Principal Fellow of the HEA and has published over 360 academic papers. Alan’s degrees are in Physics (BSc and PhD – both from the University of Edinburgh). Subsequently, he has done this...

Primary Interest … Biomedical Sensing and Actuating

Silicon technology can now be integrated with sensors of temperature, pH, oxygen concentration and of biological molecules. This allows chips to be developed that can monitor the body from the inside and in great detail. This is the principle that drove the 2013-2019, £5.2M, EPSRC Programme Grant Project, IMPACT - Implanted Microsystems for Personal Anti-Cancer Treatment.
IMPACT showed:

  1. That miniaturised Oxygen sensors can make clinically-useful measurements of pH and oxygen saturation in vitro and in small(rat) and large (sheep) animal models

    (in CMOS CIRCUITS FOR BIOLOGICAL SIGNAL PROCESSING, 2018)

  2. The sensors can also be used to monitor healing in internal, post-operative wounds – demonstrated in small (rat) and large (pig) animal models.

  3. That electrochemical sensors can be miniaturised and implanted to measure specific biomarkers, including Caspases, Trypsine and Human Neutrophil Elastase

  4. That is possible to develop an inert “pro drug” that, when injected systemically, can be activated ELECTRONICALLY by and implant chip at the site of the tumour to produce a cytotoxic drug such as Oxalyplatin (used for colorectal cancer) and Cisplatin (used for a wide range of solid cancers). This will reduce or remove the side-effects of conventional chemotherapy
