Light-sheet fluorescence microscopy is an exciting new imaging method that harnesses thin sheets of light to make images of large biological samples such as fly and fish embryos, mice and even pieces of human tissue. And its use could lead to less intrusive and more effective diagnosis for patients.

At the University of St Andrews, we have recently utilized the unusual properties of shaped laser beams to get a clearer image deeper inside specimens – using beams that bend and curve around corners and get brighter, rather than dimmer, as they travel.
