These optically barcoded nanoparticles could transform cancer diagnosis.

Blood tests using nanoparticles carrying molecules which can detect breast cancer biomarkers could save millions of lives and open the way to mass screening for many cancers.

Prof. Matt Trau, of the Australian Institute for Bioengineering & Nanotechnology at the University of Queensland, and his team are using a combination of nanotechnology and molecular biology in the project, funded by a five-year $5 million grant from the National Breast Cancer Foundation.
