  • Sensing elements and methods for making and using same
    Patent number: 5296381
    Abstract: A sensing element for sensing the concentration of an analyte in a medium is disclosed. The sensing element comprises a matrix material having at least one indicator component covalently bonded thereto. The indicator component is capable of providing a signal dependent on the concentration of a analyte in a medium. The indicator component is derived from at least one indicator compound having an aromatic ring to which is directly bonded a group including a functional portion which is conjugated relative to this aromatic ring.
    Type: Grant
    Filed: August 8, 1991
    Date of Patent: March 22, 1994
    Assignee: Minnesota Mining & Manufacturing Co.
    Inventors: Masao Yafuso, Paul F. Korkowski, Roger A. Mader, Cheng Yan, John T. Carlock
  • Nonlineaphores and polymers incorporating such nonlineaphores
    Patent number: 5256784
    Abstract: Nonlinear-optic (NLO) compositions containing functionalized merocyanine dyes, such that the molecules, comprising the NLO-active compositions have a functional group at each end of the molecule and each functional group differing in reactivity, thus permitting stepwise reaction of each functional group, and NLO-active molecules prepared from hemioxonol dyes derviatived with (meth)acrylate or (meth)acrylamide groups, and their uses in devices such as second harmonic generators or polymer integrated optics.
