Researchers are reporting the construction of what they term "artificial molecules" and say they can use the technology to engineer a new generation of nanomaterials that control and direct the energy absorbed from light.Including an antenna that can build itself. Traditional antennas increase the amount of an electromagnetic wave – such as a radio frequency – that is absorbed, and then funnel that energy to a circuit. These nanoantennas instead increased the amount of light that is absorbed and funneled it to a single site within their molecule-like complexes. This concept is already used in nature in light harvesting antennas, constituents of leaves that make photosynthesis efficient. read more
