Scientists Create Plants That Emit Light

Led by Pavlo Gordiichuk, engineers at MIT have given plants the ability to emit rechargeable light. The research stems from an emerging field called “plant nanobionics” which explores the power of plants when modified with nanoparticles. To create the plant-based lighting, researchers created a capacitor (the part of an electrical circuit that stores electricity) to store light and gradually release it over time. It’s made from phosphor, broken into nanoparticles using strontium aluminate and coated in silica to protect the plant. Embedded in the plant’s stomata (the small pores found on leaves), the particles create a thin film that absorbs photons from sunlight or LED. After 10 seconds of blue LED exposure, the manipulated plants glowed for one hour before tapering off. “If living plants could be the starting point of advanced technology, plants might replace our current unsustainable urban electrical lighting grid for the mutual benefit of all plant-dependent species—including people,” says professor of architecture at MIT and co-author of the study, Sheila Kennedy.
