Abstract: Described are devices and methods for forming one or more nanomembranes including electroactive nanomembranes within a nanowell or nanotube, or combinations thereof, in a support material. Nanopores/nanochannels can be formed by the electroactive nanomembrane within corresponding nanowells. The electroactive nanomembrane is capable of controllably altering a dimension, a composition, and/or a variety of properties in response to electrical stimuli. Various embodiments also include devices/systems and methods for using the nanomembrane-containing devices for molecular separation, purification, sensing, etc.

Abstract: The invention relates to a test system for analyzing body fluids of the type comprising a test element tape carrying a plurality of test elements, a tape deflector for the test element tape for the selective application of body fluid, and a light source as well as a detector for optically analyzing test elements to which body fluid has been applied. The tape deflector has a rotatable optical element which acts as a deflection roller during transport of the test element tape. The optical element is positioned in the optical path between the light source and the detector.
