Unique Plant with vivid Lights in the night


Perhaps in future roadway lighting will be replaced with this burning tree. Scientists succeeded in developing LED lamps made from biological.

Scientists from Academia Sinica and National Cheng Kung University in Taipei and Tainan embed-shaped gold nanoparticles glow or sea urchin known as bio LED, into plant leaves.

The new nanoparticles could replace the electric street lamps with light source of CO2 in the atmosphere. "In the future, bio LEDs can be used to make roadside trees illuminated at night," said Yen-Hsun Su. "This way we will save energy, and CO2 will be absorbed as bio-energy LED through photosynthesis."

As quoted by MSNBC, sea urchin-shaped gold nanoparticles is the key to the absorption of light, and spread abroad. Chlorophyll, photosynthesis pigments that give the characteristic green color of leaves, known for their ability to absorb certain wavelengths of light. When exposed to light with wavelengths around 400 nanometers, chlorophyll usually emit a red color.

Light purple hard to come by, especially at night when pengendera and penajan feet need it. Scientists need a source of light purple, and light sources that can be found in gold nanoparticles. When the shorter wavelengths of light on gold nanoparticles, then the leaves will emit violet light.

Scientists hope the trees are given the gold nanoparticles will produce enough light so that it can replace the electric street lamps. For now, the effect is still limited to the subject tests, water plants known as Bacopa caroliniana.

Scientists from the University of Maryland Krishanu Ray said that is something that is impossible to reproduce this tree along the road. "These trees can be used as street lights," he said. "However, it is still far to get there."
