Bioluminescent Algae Used to Create 3D-Printed Living Lights
Researchers at the University of Colorado Boulder have harnessed bioluminescent marine algae Pyrocystis lunula to create 3D-printed, electricity-free light sources. Published in Science Advances on May 6, the study demonstrates that acidic solutions can sustain the algae's glow for up to 25 minutes. The algae were embedded in a water-based gel and 3D-printed into shapes like a crescent moon and the CU Boulder logo, remaining alive for four weeks with 75% of glow retained. The team, led by Wil Srubar and Giulia Brachi, aims to develop sustainable lighting for glowsticks, deep-sea robots, or space applications. The algae also absorb carbon dioxide, offering a carbon-storing light source. Challenges remain in scaling from lab to real-world use.
