  • Patent number: 7385019
    Abstract: Water-based fluids that can viscosify under shear or can produce a gel or form a gel under shear are obtained by dissolving polymers in an aqueous phase. These polymers comprise three types of functional groups: non-ionic functional groups that are hydrosoluble at the temperature under consideration, ionic functional groups, and functional groups that are hydrophobic at the temperature under consideration. These three types of functional groups can be distributed or spread in a random distribution along the polymer chain. A slightly block distribution is acceptable. For applications to oil wells, functional groups are used which exhibit LCST (Lower Critical Solution Temperature) behavior (i.e., a low critical solution temperature) instead of hydrophobic functional groups. At temperatures below the LCST, the functional groups are hydrophobic.

  • Patent number: 7247489
    Abstract: This invention provides methods of using ion-detecting microspheres containing an ionphore and a chromoionphore in clinical laboratory instrumentation such as flow cytometry for sample analysis. In one embodiment, the microspheres are contacted with a flowing stream of a sample under conditions that allow the ion-selective ionophores to complex with the ions in the sample, and to cause deprotonation of the chromoionophore. The complexes are then exposed to an excitation wavelength light source suitable for exciting the deprotonated chromoionophore to emit a fluorescence signal pattern. Detection of the fluorescence signal pattern emitted by the deprotonated chromoionophore in microspheres containing the complexes allows for determination of the presence of the target ions in the sample. In one embodiment, lead ion-detecting microspheres are provided that can detect nanomolar levels of lead ions with response times on the order of minutes.
