Turning trees into street lights...!

Share |

This is one discovery, when properly developed and employed, is going to change the whole world.
This will provide one revolutionary solution for controlling pollution and also to save a significant amount of power...!! Its another magic of nano technology...:)

Now a days there is a very large increase in cutting down trees for some construction or road widening purposes. This decrease in no. of trees is as everybody knows, is very dangerous. Trees provide us oxygen to live and we are killing them. How foolish are we...??!!! don't you think...?

This motivated Post-doctor Yen-Hsun Su of Research Center for Applied Science (RCAS), Academia Sinica, Taiwan, to think of this revolutionary idea and also making it a reality...!!

This brilliant discovery is using gold nanoparticles to induce luminescence in leaves...!!!

How is it possible.....??

well, Yen-Hsun Su implanted gold nanoparticles into Bacopa caroliniana plants and found that, when exposed to high wavelength ultraviolet light, the gold nanoparticles can produce a blue-violet fluorescence that triggers a red emission of the surrounding chlorophyll.

Assistant Prof. Shih-Hui Chang of Institute of Electro-Optical Science and Engineering, upon learning the discovery said,"Light emitting diode (LED) has replaced traditional light source in many display panels and street lights on the road. A lot of light emitting diode, especially white light emitting diode, uses phosphor powder to stimulate light of different wavelengths. However, phosphor powder is highly toxic and its price is expensive. As a result, Dr. Yen-Hsun Wu had the idea to discover a method which is less toxic to replace phosphor powder which can harm human bodies and cause environmental pollution"

In an interview with the 'Chemistry World' Yen-Hsun Su stated "In the future, bio-LED could be used to make roadside trees luminescent at night. This will save energy and absorb CO2 as the bio-LED luminescence will cause the chloroplast to conduct photosynthesis,"

The invention needs to be developed a lot. But anyway, I think its a billion dollar idea...! Lets hope the days of us seeing the roadside trees illuminating, are not far...:)
