Interview: Nanosilicon for nanomedicine: a step towards biodegradable electronic implants?

Abstract

Leigh Canham received his BSc degree in physics from University College London (London, UK) in 1979 and his PhD in solid state physics from King’s College London (London, UK). He now has over 30 years of experience conducting research on widely differing aspects of silicon technology. Two key personal discoveries – that nanostructured silicon can emit visible light efficiently (1990) and can be rendered medically biodegradable (1995) – have had significant academic (>15,000 citations) and commercial (multiple companies created) impact. Professor Canham is a scientist who is devoted to finding novel properties and uses for semiconductors that already pervade our everyday lives. He has 13 years of experience of start up company management, right through from cofounding with seed venture capital finance to NASDAQ listing. He has served on the board of two companies based in England, UK, one in Singapore and one in Australia. Since 1999, he has held an Honorary Professorship at the School of Physics, University of Birmingham (Birmingham, UK) for his work on luminescent silicon. In 2011, Leigh was a shortlisted finalist for the European Inventor of the Year Award from the European Patent Office for his work on biodegradable silicon. In 2012, he became a Thomson Reuters Citation Laureate for his work on luminescent silicon. Professor Canham has authored over 150 peer-reviewed papers and has more than 100 granted patents worldwide.
