Scientists at MIT have successfully injected nanoparticles into plants to give them glow in the dark properties, for the second time. The strontium aluminate nanoparticles are coated in silica so as not to damage the plant. Just 10 seconds of exposure to LED or sunlight cause the plants to glow green for up to an hour, at a brightness ten times more than the previous experiment. The plan is to be able to use these glowing plants as passive lighting in outdoor areas, thus reducing the need for street lighting.
