Nanotechnology and Biosensors

By Michael Edmonds 18/09/2012

Last night I went to a talk on “Nanotechnology & Biosensors: From Detecting Small Molecules & Drugs to the Monitoring of the Activity of Whole Cells” given by Professor Justin Gooding from the University of New South Wales in Sydney. It was fascinating. The ability to design nanoscopic structures which can detect and produce a signal when they come in contact with various molecular entities has great potential in many fields including medicine. Professor Gooding is also a director of the Australian Centre for Nanomedicine.

One biosensor example that has already been commercialised by one of Professor Gooding’s former students are glucose monitors for diabetics.

Professor Gooding also demonstrated their latest design for a glucose monitor – a small attachment which clips onto the bottom of an iPhone. Blood is then placed on a biosensor strip which is inserted into the attachment, and software in the iPhone interprets the results. The iPhone stores the data, analyses it, with the possibility that it could be transmitted directly to the dabetics doctor.

Absolutely fascinating.

Professor Gooding is giving a series of talks to branches of the New Zealand Institute of Chemistry around the North Island later this week. If anyone is interested I can put them in touch with those running these events.
