The Centre of Biophotonics (CoB) at the University of St Andrews was established in 2019 with the mission of promoting interdisciplinary research and training at the interface between advanced optical imaging, photonics and biomedical sciences. The Centre integrates researchers across four schools (Physics and Astronomy, Medicine, Biology and Psychology and Neuroscience) and builds on existing strengths in the development and application of light based technologies to investigate biological process at molecular, cellular and tissue scales. The CoB brings together more than 20 research groups around three main themes: imaging across temporal and spatial scales, mechanobiology and neurophotonics. Thus, CoB addresses important questions to improve human health including the origins of cardiovascular diseases, cancer, neurological disorders and the advance in the fight against bacterial and viral pathogens. The CoB is also strongly committed to translational research and the dissemination of technologies emerging from the Centre in collaboration with other institutions and industrial partners.
Seeing is believing and light-based imaging technologies are, now more than ever, uniquely positioned to unveil the mechanisms of life as well as disease. Building on more than 20 years of light-based innovation for the biosciences and by collaborating across disciplines and recruiting the best talents, we aim to watch these processes unfolding in real time, from the molecular and cellular scales, to the whole-organism level.

CoB MRC AWARD
Congratulations to Dr John Danial for the awarding of an MRC Career Development Award (£1.8M fEC) to work on the development of single-molecule imaging methods for structral fingerprinting of single amyloid fibrils in human samples. The award will contribute to connect the dots between structural biology and clinical diagnostics to understand and diagnose neurodegenerative diseases with unprecedented detail.
Excellent news John!

2025 CoB BIOPHOTONICS SUMMER SCHOOL
Following the success of the 1st St Andrews Biophotonics Summer School in June 2024, we are please to announce that the 2nd edition will be running from the 23rd to the 27th June 2025.
Examples of feedback from attendees to last year summer school include:
Experimental sessions were a great immersion into real bioimaging, very helpful to see other methods than everyday lab routine. Overall instructors were very helpful and supportive. Would definitely recommend this to colleagues.

CoB participating Schools
CoB BioLight seminars
27th May 2025: Defining mechanisms of blood-brain barrier dysfunction in neurodegenerative diseases using advanced organ-on-a-chip model
Speaker: Dr. Mootaz Salman – Group Leader in Cellular Neuroscience and MRC Career Development Fellow. University of Oxford.
The seminar will be on Tuesday 27th May in the BMS seminar room at 1pm.
Host: Dr Juan Varela, sponsor: Alzheimer’s Research UK Scottish Network.

Dr Mootaz Salman is a Research Fellow at Wolfson College in Oxford. His group investigates mechanisms of blood-brain barrier (dys)function in neurodegenerative diseases and brain injuries, using patient-derived stem cells. They design and build innovative dynamic 3D multicellular in vitro models including organ-on-a-chip and organoids to accurately recapitulate the brain and blood-brain barrier function under mechanobiological stimuli, neuroinflammation and other neurodegenerative-relevant conditions.
Dr Salman was awarded multiple accolades including the International Society of Neurochemistry (ISN) Young Neuroscientist Lectureship Award in 2022, the Society for Experimental Biology (SEB) 2024 President’s Medal for the Cell Biology Section, Alzheimer’s Research UK (ARUK) David Hague Early Career Investigator of the Year in 2024, and the Inaugural ALBA-Roche Research Prize for Excellence in Neuroscience 2024.

28th May 2025: Phenotypic inheritance drives heteroresistance to antibiotics in bacteria
Speaker: Dr. Minsu Kim – Department of Physics, Emory University, USA
The seminar will be on Wednesday 28th May in the BMS seminar room at 1pm.
Host: Dr. Paolo Annibale

Phenotype is often treated as a static reflection of genotype. A major theme in my group is to understand how phenotypes change without mutations, seeking to uncover the non-genetic rules that govern cellular behavior. In this talk, I will focus on bacterial responses to antibiotics. We previously found that antibiotics trigger population fluctuations in an antibiotic-susceptible bacterial population. Single-cell analyses of these fluctuations revealed a non-genetic (hence phenotypic), dynamically inherited form of antibiotic resistance, giving rise to an enigmatic phenomenon known as heteroresistance. We further isolate and examine heteroresistant clinical isolates to uncover their underlying molecular mechanisms and adaptive significance.

4th June 2025: Photon-Resolved Microscopy: Laser-Scanning Microscopy with SPAD array detector.
Speaker: Dr Giuseppe Vicidomini, Italian Institute of Technology, Genoa, Italy
The Seminar will be on Wednesday 4th June, 12.00 pm, BMS Lecture Theatre
Host: Dr. Paolo Annibale

Fluorescence microscopy is a powerful tool for studying biological structures and functions within living systems with minimal invasiveness. However, its ability to resolve many fundamental biological processes remains limited. To tackle these challenges, our group has introduced a novel class of single-photon detector arrays—the asynchronous read-out single-photon avalanche diode (SPAD) array detector—which offers a new approach to pushing the boundaries of fluorescence microscopy. This detector enables a new imaging paradigm, photon-resolved microscopy, where fluorescence photons are recorded individually and assigned multiple spatiotemporal signatures that conventional detectors cannot capture.
We first demonstrate how photon-resolved microscopy enhances confocal laser-scanning microscopy, one of the most widely used fluorescence imaging techniques. We then explore its synergies with advanced methods, including super-resolution microscopy, single-molecule techniques, and spectroscopy, further expanding the capabilities of fluorescence microscopy assays.
This paradigm opens exciting new avenues for studying complex biological processes with unprecedented detail.
