€1.5m grant for major work with luminescent jellyfish

A researcher at the University of St Andrews in the UK has been awarded a €1.5m grant by the European Research Council to further advance groundbreaking work with bioluminescent jellyfish.

The five year ‘Advanced Bioderived and Biocompatible Lasers’ (ABLASE) project led by Professor Malte Gather starts work this month and will develop lasers based on single cells. In earlier research, Gather found that the green fluorescent protein molecules jellyfish produce can be used to turn individual human kidney cells into tiny lasers, a discovery that earned an entry in the Guinness World Records for the first living laser. Recent work has involved developing tiny solid-state lasers with record performance from fluorescent proteins found in the jellyfish.

Commenting, Gather said: “Both the living lasers based on single cells and the solid-state protein lasers are intrinsically biocompatible, thus offering unique properties not shared by any existing laser. However, the physical processes involved in lasing from fluorescent proteins remain poorly understood and so far biological lasers rely on impractical resonators for optical feedback.”

Under the ABLASE project, the Soft Matter Photonics Group led by Gather will develop for the first time a detailed understanding of stimulated emission and lasing in fluorescent proteins. Building on this, the team will then develop applications of biological lasers for biomedical research, where they are expected to serve as powerful microscopic and biocompatible imaging probes and as sensors for biomolecules. The project is interdisciplinary by its very nature, bridging photonics, genetic engineering and material science.
