Scientists make wood glow with 2,400-year-old honey fungus in a scientific adventure | The biohybrid of fungus and wood, developed in the lab, produces green light after being incubated for three months, with plans to increase its luminosity further.
A team from Empa is creating luminous wood by using honey fungus, which glows thanks to a natural bioluminescence process.
Looking ahead, the team emphasized that future advanced materials must possess “smart” capabilities, such as the ability to self-heal, respond to their environment, and change state. When it came into contact with air, it triggered a chemical reaction involving caffeic acid that made the wood reach its maximum bright green luminosity in about 10 hours in a process that lasted an impressive 10 days. Unlocking these bioluminescent mechanisms could bring an electricity-free light source into the world for human consumption with a low-energy requirement, according to study authors.
