  • Patent number: 6203758
    Abstract: A micro-circuit for performing analyses of multimolecular interactions and for performing molecular syntheses, comprising: (a) a support; (b) at least one micro-electrode attached to the support, the micro-electrode being selectively electronically activated and the micro-electrode having a protective layer which is removable; (c) a binding entity for attachment to the at least one micro-electrode, the binding entity being capable of attachment to at least one micro-electrode when the protective layer has been removed; and (d) a power source being operatively connected to at least one micro-electrode for electronically activating at least one micro-electrode. The micro-circuit of the present invention also includes embodiments featuring a micro-circuit reader for detecting the interaction of the binding entity to a complementary probe, as well as methods for making and using the micro-circuit of the present invention.

  • Patent number: 6200553
    Abstract: The application of a soluble calcium compound and the further application of a suitable fluoride material accomplish calcium remineralization of fingernails. The calcium and fluoride preparations are kept separate until used. The calcium preparation is rubbed into the nail prior to the application of the fluoride; the fluoride then combines with the calcium applied in the first step within the nail allowing the nail to become harder and stronger.

  • Patent number: 6177000
    Abstract: A biosensor has a lipid membrane (7) containing gated ion channels sensitive to the presence or otherwise of an analyte molecule in a sample applied, in use, to a first side of the lipid membrane (7). The lipid membrane (7) is disposed between a pair of electrodes (1, 2) in which a first layer of porous gel (4) is applied to the first side of the lipid membrane (7).

  • Patent number: 6177126
    Abstract: A process for producing a material for sealing and/or healing wounds fills a liquid composition into a container having two or more plates. At least two of the plates are perforated with one or more flow-through holes. At least one of the perforated plates is movable relative to another of the perforated plates. A suitable carrier is transported below the container in transport direction. The perforated plates are then continuously moved relative to each other so as to allow the liquid composition to drip onto the carrier being transported below the container. The liquid composition can thus be substantially evenly applied to the carrier.
