Storage, retrieval and erasure of optical information in bacteriorhodopsin (bR) films by alteration of the bR's absorption spectrum by photo-induction and by application and switching of an electrical field.

Method and apparatus for reversible optical data storage

Sensors responsive to small changes in the concentration of chemical species are disclosed, comprising a mechanicochemically responsive polymeric film capable of expansion or contraction in response to a change in its chemical environment, either operatively coupled to a transducer capable of directly converting the expansion or contraction to a measurable electrical or optical response, or adhered to a second inert polymeric strip, or doped with a conductive material.
