MIT Just Created Living Plants That Glow Like A Lamp, And Could Grow Glowing Trees To Replace Streetlights



Roads of the future could be lit by glowing trees instead of streetlamps, thanks to a breakthrough in creating bioluminescent plants. Experts injected specialized nanoparticles into the leaves of a watercress plant, which caused it to give off a dim light for nearly four hours. This could solve lots of problems.



The chemical involved, which produced enough light to read a book by, is the same as is used by fireflies to create their characteristic shine. To create their glowing plants, engineers from the Massachusetts Institute of Technology (MIT) turned to an enzyme called luciferase. Luciferase acts on a molecule called luciferin, causing it to emit light.

Another molecule called Co-enzyme A helps the process along by removing a reaction byproduct that can inhibit luciferase activity. The MIT team packaged each of these components into a different type of nanoparticle carrier.



The nanoparticles help them to get to the right part of the plant and also prevent them from building to concentrations that could be toxic to the plants. The result was a watercress plant that functioned like a desk lamp.







Researchers believe with further tweaking, the technology could also be used to provide lights bright enough to illuminate a workspace or even an entire street, as well as low-intensity indoor lighting.

 





Michael Strano, professor of chemical engineering at MIT and the senior author of the study, said: 'the vision is to make a plant that will function as a desk lamp — a lamp that you don't have to plug in. The light is ultimately powered by the energy metabolism of the plant itself. Our work very seriously opens up the doorway to streetlamps that are nothing but treated trees, and to indirect lighting around homes.'





The full findings of the study were published in the American Chemical Society journal Nano Letters. What do you think about this development?
