The same techniques are now used to cut out sheets of graphene, one atom thick. The products respond to vibrations and changes in light and temperature, responding with very small-scale movements. There are endless applications in sensing, manipulating, and complex nanoscale robotics. Applications are in the work of MK Blees et al, Nature 524, 204 – 207, August 13.
