Technology Lighting the path to disease detection

Lighting the path to disease detection

Using light as a diagnostic tool in medicine has just become even more illuminating.

An international team including researchers at Swinburne University of Technology and The Australian National University has developed some brilliant new technology.

It has the potential to revolutionise next-generation bio-sensing products and could be used to help diagnose disease from body fluids.

The researchers have turbo charged a device known as a metasurface that traps powerful infrared light.

The nanostructure, along with a bio sensor, can harness the concentrated light, to recognise biomarkers in diseased cells.

“For example, it could be applied to build an ultra-compact and extremely sensitive diagnostic chip that can detect disease in small samples of blood or saliva, helping people monitor their health in real time,” said Dr Fengchun Zhang from South China Normal University, a co-author of the study.
