A team of researchers do a study of a plant that can emit light by itself

Reported from Science Alert

MIT Chemical Engineering Professor Michael Strano, who is also a researcher in the research, said: "The goal of us is to create plants that will serve as table lamps that no longer need electricity, the light comes from the metabolism of the plant itself.

The results, that published in the journal Nano Letters, explain that the MIT team used plant nanobionic techniques, a technique to infuse plants with nanoparticles that have been programmed to do a specific task, producing their luminous plants.

By making the nanoparticles present in a liquid solution. Then the plant is immersed in the solution and given pressure. It will make stomata, small pores in plants, open and let nanoparticles in.

In order to make the plant radiant, the team filled up nano particles with luciferase and luciferin molecules. These two chemicals are light producers in fireflies and marine animals such as jellyfish.

They also added a molecule called co-enzyme A, which eliminates the chemical reaction between luciferase and luciferin that can interfere with the emerging light.

Using Nasturtium officinale as an experiment, the team found that the resulting light was low enough. Nevertheless, the team claimed to be able to raise the level of light produced by plants, and able to survive for 3.5 hours.

In addition, they also show that light can be switched off by infusing the luciferase inhibitor.
Now the team hopes to develop a plant that can turn off its own light when the sun rises.

They hope the results of this research can help our dependence on light from electricity.

"The results of our work pave the way to replace streetlights into trees," said Strano.
