Research on automated cancer screening featured in Advanced Science News

Our recent publication, “Towards automated cancer screening: Label-free classification of fixed cell samples using wavelength modulated Raman spectroscopy” from Journal of Biophotonics, has been featured in Advanced Science News.

The article states “The introduction of national screening programs to detect (pre-)cancerous processes, such as the Papanicoloau (‘Pap’) test and mammogram, have achieved considerable success and are estimated to prevent, for example, 4,500 and 1,300 deaths in the UK every year from cervical and breast cancer, respectively.”

These programs require a great deal of investment and have limited quantitative accuracy. The article identifies our method as one “with the potential to deliver a broader scope and automated classification”.

New class of laser wavemeter breaks the glass ceiling

The precise wavelength of a laser is important in numerous applications, but measuring changes of wavelength to one part in ten thousand million has been quite demanding. Our group has invented a new technique for doing such measurements based on the random scattering of laser light from a rough surface. This breakthrough could revolutionise the use of lasers in certain applications in quantum technologies and in healthcare.
