Refining hardwood by bioluminescence

Since more and more deciduous trees are being planted in Swiss forests, whose wood is often burned directly, innovative ideas for a cascade use are in high demand in order to utilize Swiss hardwood more sustainably. Empa researchers are therefore equipping wood with new functionalities. Their latest coup: wood that can glow in the dark.

Soft, living materials made with algae glow under stress

Researchers have developed soft yet durable 3D-printed materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego’s beaches.
