3D-geprinte algen als duurzaam alternatief voor elektrisch licht

Researchers at the University of Colorado Boulder have developed a method to sustain the bioluminescence of algae by using chemical solutions instead of physical agitation. By embedding the organisms in 3D-printed hydrogels and adjusting pH levels with acidic solutions, they created living structures that glow for up to 25 minutes and remain viable for weeks. This breakthrough could potentially replace electricity-dependent lighting with a carbon-negative biological alternative in the future.
