Abstract
A self-assembled DNA-based molecular device is described which can be switched between three distinct mechanical states. The device consists of two supramolecular “arms” connected by a hinge. The arms can be in a closed, relaxed, or stretched configuration. The operation of the device is monitored by fluorescence resonance energy transfer. Variations in the design of the device have a strong influence on the operation kinetics of the device.Keywords
