Physicist Professor Dayong Jin has been awarded the Malcolm McIntosh Prize for Physical Scientist of the Year in the 2017 Prime Minister’s Prizes for Science for creating new technologies to image the processes of life. The prize recognises exceptional achievement in science that benefits, or has the potential to benefit, human welfare or society.

Professor Jin, who is the Director of the ARC Research Hub for Integrated Device and End-user Analysis at Low-levels at the University of Technology Sydney, has created new kinds of microscopes that allow us to watch molecules at work inside living cells.

Over the next five years, the UTS physicist will use the discoveries he has made in super-resolution imaging and high-performance sensors – namely Super Dots and Hyper Dots – to meet his “ambitious goal” of being able to zoom in on the workings of a single human cell.

“Human beings have a long history of making and using maps. Satellite technology has given us the images for global maps while cameras used at street level allow us to zoom in and know exactly where we are,” said Professor Jin.

Heart-attack risk among people with diabetes and the mechanisms that make bacteria resistant to antibiotics are two urgent medical issues in his sights.
