Engineers Place Thousands of Nanoscale Molecular Devices in Precise Orientation

Researchers placed more than 3,000 glowing moon-shaped nanoscale molecular devices into a flower-shaped instrument for indicating the polarization of light. The “moons” in each of the 12 petals points in a different direction, and only glows when struck by polarized light matching its orientation. The end result is a flower whose petals light up in […]
