“Dr Yen-Hsun Su from the National Cheng Kung University in Taiwan has discovered that the leaves of the Bacopa caroliniana tree can produce a red emission in chlorophyll upon the addition of gold particles. This amazing fusion of nanotechnology with nature can help the environment in many different ways; roads can now be well-lit without having to consume a significant amount of electricity, thus dramatically cutting light pollution and carbon emission.” – PSFK
