  • Diamond or diamond like carbon coated chemical sensors and a method of making same
    Patent number: 6320295
    Abstract: A water vapor insensitive and corrosion resistant chemical or biochemical sensor device, including a transducer, coated with a protective coating of diamond or a diamond-like carbon, preferably by a pulsed laser deposition technique. The surface of the protective coating is coated with a chemoselective or bioselective absorption material or film.
    Type: Grant

    Date of Patent: November 20, 2001
    Inventors: Robert Andrew McGill, Paul Christopher Dorsey, Douglas Brian Chrisey
  • Method of producing a film coating by matrix assisted pulsed laser deposition
    Patent number: 6025036
    Abstract: A film of a coating material is produced on a substrate by a pulsed laser deposition method in which the material that forms the coating material is first combined with a matrix material to form a target. The target is then exposed to a source of laser energy to desorb the matrix material from the target and lift the coating material from the surface of the target. The target and the substrate are oriented with respect to each other so that the lifted coating material is deposited as a film upon said substrate. The matrix material is selected to have the property of being more volatile than the coating material and less likely than the coating material to adhere to the substrate. The matrix material is further selected as having the property such that when the target is exposed to a source of laser energy, the matrix material desorbs from the target and lifts the coating material from the surface of the target.
