Seeing Life at Explorathon 18, 29th September 2018

Over 400 visitors to Explorathon 18 at Dundee Science Centre investigated how light is changing the way we look at biology and medicine.

The Seeing Life through a New Light activities were delivered by group members Adrià Montalbán, Philip Wijesinghe, and Yoshi Arita, as well as volunteers from the Gather Lab.

The event showcased how simple optical principles could be used for imaging and manipulation of cells and tissues.

Our star attraction is our new acoustic levitator (which you can make for yourself at instructables.com). It helps demonstrate how light and sound can be used to trap and control small objects. Read the original paper on the device in Rev. Sci. Instrum.

We are hiring: Vacancy for 1 postdoc in spectroscopy and imaging

We are hiring!

The Optical Manipulation Group is seeking a one-year Research Fellow in experimental photonics dedicated to Raman microscopy for applications in biomedicine and also for the oil and gas industry. You should have research experience in optical microscopy, supported by a good publication record. Experimental expertise in Raman analysis combined with appropriate knowledge of numerical data analysis is desirable.

Congratulations to Laura O’Donnell

Congratulations go out to all our new graduates, especially to Laura O’Donnell BSc who was awarded the prize for the best BSc physics final year project.

Laura’s project in the Optical Manipulation Group was supervised by Prof. Kishan Dholakia and Dr Graham Bruce (pictured).

Her project was focused on “Multiple wavelength measurements with a speckle-based wavemeter” and builds on our previous work on sub-femtometre resolved speckle-based wavemeters.

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”.

Prof. Dholakia awarded SPIE Dennis Gabor Award 2018

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.
