Taiwanese scientists have invented a method to turn the leaves into bio-photodiode emitting bright blue-white light. In the future, it is likely that the two sides of the street will grow brightly colored trees replacing street lamps.
Recently, a group of scientists led by Dr. SuYen-hsun, Chen Kung University, Taiwan has been able to create lamps of plant origin. They grafted nanoparticles, which are no more than 5 nanometers in size, into the Leilium leaf plant (bacopa caroliniana - a perennial aquatic plant that lives in the marshes of the sea, often taken as a pot plant) At that time, the 'enriched ' leaves of precious metals began to glow red in a rather intense light.
Chlorophyl has been known for a long time, a plant that uses solar energy to synthesize organic substances - capable of not only absorbing light but also emitting light. To confirm this, you can do a simple experiment yourself: take some green leafy vegetables and dip a little alcohol and pour the chlorophyl dissolved solution. On the filter paper you can see the glowing red spots are very weak.
The most interesting thing is, glowing occurs not only during the day, but at night too, which means that there is no need to stimulate chlorophyl with sunlight. That light helped the animals to function at night to live in the forest like geckos, moths . oriented in the dark. The lights are so weak that the eyes cannot be seen. In addition, chlorophyl may not glow continuously - but when ' on ', when ' off '.
So are shrubs and woody plants. But with the peddler above, living in the water, besides the chlorophyl red, it also emitted blue. But blue light is also weak and invisible. How to make that light stronger? Dr. Su devised a way to use tiny gold particles because they have the ability to increase the intensity of any light on their surface.
The " gold-plated " child has enough porosity to adsorb any microparticles dissolved in water, when tiny gold particles gather in chloroplasts (chloroplast, which contains chlorophyl), the plant will release Light out blue, enough brightness to read books.

Light is amplified by nanoparticles. Scientists explain that the gold particles they use are very special: they are made like a sea urchin. Therefore, they capture biological photovoltaic devices that work continuously, without turning on and off as if they were not processed in gold.
According to Dr. Su, his research has the potential to apply in practice. For example, this invention can be used to create glowing trees planted along the highway to illuminate at night instead of the rows of lampposts in use, but the efficiency is not inferior. The plants also have another benefit - they purify, make the atmosphere fresher because of the elimination of toxic waste emitted by cars and the assimilation of carbon dioxide gas.
You may wonder, if this idea is implemented, chlorophyl due to the roadside trees do not emit blue light, but red light is a light that is not cool against the physiology of the eyes and is not familiar with the participants. traffic. But scientists argue that solving this problem is not complicated. Only by acquiring the genetic engineering of the genome of the juvenile plant under water to plants growing on land, it is not difficult to obtain ' necessary ' chlorophyl.
At that time, the fairy tale of childhood about glowing trees will become normal, and the fanciful image of these beautiful trees does not lose to the fairy tale. (Of course, it is necessary to protect the rows of gold inlaid trees, because even if nano gold has an insignificant amount of gold, it is easy to be interrupted 'as a souvenir ').
