UNSW Scientia Professor Justin Gooding was awarded the 2017 Liversidge Medal by the Royal Society of NSW for his research in chemistry.

He will deliver the Liversidge Lecture on Thursday evening 11 May.

Abstract:

Biosensors are solid state analytical devices made by integrating a biological molecule that can recognise a biomarker of interest with a signal transducer, such as an electrode or optical instrument.

The classical examples of such devices are the glucose meters that have revolutionised the lives of diabetic patients, and pregnancy test kits. There is a whole family of related devices developed for uses ranging from disease diagnosis to water quality testing.

This presentation will cover the state-of-the-art research in this field, explore some of the challenges to wider adoption of such devices in daily life, and outline the work of the Smart Materials and Surfaces research group at UNSW in this area.

It will then focus on advances in surface chemistry and nanotechnology that will lead to the next generation of sensors that detect single molecules and cells. Such devices not only represent the ultimate sensor in being able to detect a single thing, but will solve many challenges with existing sensor technologies.

By being able to detect many single moelcules or cells, such that the devices essentially count the number of entities to be measured, they will solve the main challenges in sensors of calibration and nonspecific signals, as well as create a whole new type of sensor.

The presentation will conclude with a discussion of some of our work on bringing this exciting vision of our sensing future towards a reality.
