Microscopic sensors that are as thin as a strand of hair but capable of taking multiple measurements simultaneously could revolutionize the diagnosis and monitoring of diseases like cancer. Researchers from Adelaide University’s Institute for Photonics and Advanced Sensing and the University of Stuttgart in Germany worked together to develop the tiny sensors using state-of-the-art, ultrafast 3D micro-printing technology.

The unique sensors target specific biomarkers and are printed directly onto the tip of optical fibers. They’re able to monitor several signals at the same time, including temperature and chemical changes. The paper is published in the journal Advanced Optical Materials.

“This breakthrough could lead to next-generation medical tools that track disease, guide treatment and monitor the body in real time,” said Associate Professor Shahraam Afshar, the project’s lead researcher from Adelaide University’s Institute for Photonics and Advanced Sensing.
