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.

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.

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”.

Kishan Dholakia, University of St Andrews, School of Physics & Astronomy, North Haugh, St. Andrews, Fife, is the 2018 winner of the Dennis Gabor Award in recognition of his work in optical beam shaping using dynamic and static diffractive optics. This work has led to paradigm shifts in manipulation, nano-surgery and imaging and has enabled new routes for the understanding of holographic light fields for a range of applications.

Professor Kishan Dholakia of this School has been awarded the Institute of Physics Thomas Young Medal and Prize for 2017. This prestigious award is for his “contributions to the field of optical micromanipulation using shaped light fields in liquid, air and vacuum”.
The citation goes on to talk about Prof Dholakia’s “internationally acknowledged and distinguished reputation for his work … including new insights into the understanding of complex light fields and their propagation”.

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.
