Researchers have illuminated wood using natural materials, paving the way for energy-efficient lighting and furniture in the home.
The scientists from Empa’s Cellulose & Wood Materials lab in Switzerland were inspired by bioluminescent plants, enclosing balsa wood in a container with mushroom for three months to absorb water.
This experiment illuminated the wood with a green glow by exposing it to oxygen and activating the luciferase enzyme using fungus.
While the light itself lasts for around 10 days, the wood keeps its structural integrity because of the chemical compounds found in the mushrooms and has been published in a landmark study in Advanced Science.
The researchers hope to increase the lifespan of the glow to provide a passive lighting option for homes, furniture and even accessories in response to climate change.
As well as 'dead' wood, other research has investigated making living plants that glow for the same goals.
