Nanowires sense blood anti-bodies - University of Southampton

Abstract:
The University of Southampton is to develop a bio-medical sensor based on silicon nanowires.

"You can functionalise the wire by coating it with a chemical that will attract a particular anti-body," Professor Peter Ashburn told Electronics Weekly. "Anti-bodies are usually charged, so they alter conduction in the nanowire, which you can detect."

Beyond the sensing structure, which the team aims to have prototyped in between 12 and 18 months, the three-year plan includes integrating electronics and micro-fluidics to produce a self-contained device that allows routine blood tests to be completed in a doctor's surgery.
