Interlocked molecular and supramolecular actuators based on rotaxanes can act as gatekeepers at the entrances to nanopores in silica, into which guest dye molecules can be uploaded and then released on demand. Such actuators, or nanovalves (shown in the figure), can be operated using a wide range of stimuli, and can be regarded as the prototypes of highly controllable drug-delivery systems.
