Light without electricity? Glowing algae could make it possible
Summary
CU Boulder reports a Science Advances study where bioluminescent algae (Pyrocystis lunula) are triggered to glow using simple chemical cues within a hydrogel to create living light materials. The work demonstrates sustained luminescence for extended periods, demonstrated via 3D-printed structures, and outlines potential uses in autonomous robots, living sensors for water quality, and carbon capture benefits. The research highlights both the novelty and practical challenges of integrating living organisms into functional lighting and sensing materials.
