Gold Nano Particle Bio LED Lights


Researchers in Taiwan at the Academia Sinica in Taipei and the National Cheng Kung University in Tainan have synthesised gold nanoparticles and implanted them into leaves of the Bacopa caroliniana plant to induce bio-luminescence light.

Using sea-urchin-shaped nanoparticles (dubbed nano-sea-urchins or NSUs), the team was able to excite chlorophyll in the leaves to emit red light.

The bio-LEDs (light emitting diodes) might eventually be used to make trees lining roads provide street lighting, and since the light causes the chloroplast to conduct photosynthesis no energy source is needed and the plant will absorb CO2 for the process, which does not normally occur at night.

The team are looking to apply the same technique to other plant molecules and to improve the efficiency of the process. Their work was reported in the journal Nanoscale.
