Elegant control: A DNA actuator based on the most fundamental motif in DNA nanotechnology, the double crossover tile, has a linear sliding-gauge type of motion among eleven different states (see picture). The actuator has the ability to fine-tune the distances between attached components (resolution of less than 1 nm) for both physical studies and chemical control.
