Nano Ribbons Coil into Rings

Researchers from the Georgia Institute of Technology have found a way to coax microscopic zinc oxide ribbons to spontaneously coil, slinky-like, into perfect rings. The rings are single-crystal material and are 300 nanometers wide, 10 nanometers thick and three microns wide. The rings are a little more than half the girth of a red blood cell. The tiny rings are potentially useful as parts, including sensors, resonators, transducers and actuators, in nanoscale machines.
