Bio-inspired nanoantennas for light emission

Just as radio antennas amplify the signals of our mobile phones and televisions, the same principle can apply to light. For the first time, researchers have succeeded in producing a nanoantenna from short strands of DNA, two gold nanoparticles and a small fluorescent molecule that captures and emits light. This work could in the longer term lead to the development of more efficient light-emitting diodes, more compact solar cells or even be used in quantum cryptography.
