Research on advanced imaging featured in The Conversation
Our recent publication “Light-sheet microscopy with attenuation-compensated propagation-invariant beams” has been highlighted in The Conversation.
Dr Jonathan Nylk, the lead author of the study, was invited to write the article which gives an overview of light-sheet microscopy and an introduction the use of structured photonics in this area.

TRAFIX: New imaging technique shortlisted for Converge Challenge
Congratulations to group member Adrià Escobet-Montalbán, whose TRAFIX project on imaging deeper within turbid media has been shortlisted for Scotland’s largest entrepeneurship award, the Converge Challenge.
Adrià’s work enables images to be acquired from deep within turbid specimens such as brain tissue and could have a major impact on neuroscience studies of alzheimer’s and Parkinson’s diseases and cancer. The new technique could be suitable for clinical use as well as basic research.

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”.
