  • Patent number: 6325977
    Abstract: An optical detection system. The optical detection system includes an integrated circuit, photosensors, a passivation layer formed above the photosensors, and test sites formed on the passivation layer. The test sites include test probes of organic material that are able to bind with target organic molecules. The combination of the test probes and target organic molecules can be activated such that light is given off from the test sites in proportion to the concentration of target molecules. Light given off from the test sites is detected by the photosensors that are present below the passivation layer. The photosensors generate electronic signals in proportion to the amount of light received from the test sites. The electronic signals are then transmitted from the photosensors to the integrated circuit for signal processing. Signal processing within the integrated circuit can enhance the quality of the electronic signals generated by the photosensors.

  • Patent number: 6306657
    Abstract: The present invention provides a method for simplifying and significantly enhancing the sensitivity of nucleic acid hybridization assays. A method is described whereby a single-stranded primary nucleic acid sequence that includes a region of sequences complementary to a single-stranded target nucleic acid sequence is hybridized to the target molecule. Stability of the double-stranded complex thereby formed can be enhanced by using RNA as the probe if DNA is the target or DNA as the probe if RNA is the target. The probe-target complex is subsequently immunocaptured for detection. After washing away extraneous material, a secondary nucleic acid sequence containing many repeating sequence units is hybridized to the probe component of the immobilized probe-target complex. Detection occurs following hybridization of many labelled nucleic acid sequence probes to each of the repeating sequence units of a nucleic acid amplification probe.

  • Patent number: 6277605
    Abstract: The present invention provides an alternative PCR amplification which does not draw upon the use of thermostable DNA polymerases. It provides means for the controlled manipulation of denaturing conditions which do not demand the use of high denaturing temperature. More particularly, it provides means for the controlled oscillation of divalent metal ions, preferably of divalent metal ions such as Cu2+, Zn2+, Mn2+ and Cd2+, which are known to destabilize the DNA helix and thereby decrease the melting temperature of the DNA helix. The invention also provides methods for the automatization of this process. For instance, by means of cathodic reduction of the divalent metal species the concentration can be decreased to levels that allows for reannealing of separated sands with the primers; while oxidation of deposited metals or oxidation of monovalent metal ions, can restore the initially high concentration that allows for separation of both strands that make up the DNA helix.

  • Patent number: 6008373
    Abstract: The present invention provides low molecular weight fluorescent labeling complexes with large wavelength shifts between absorption of one dye in the complex and emission from another dye in the complex. These complexes can be used, for example, for multiparameter fluorescence cell analysis using a single excitation wavelength. The low molecular weight of the complex permits materials labeled with the complex to penetrate cell structures for use as probes. The labeling complexes are synthesized by covalently attaching through linkers at least one cyanine fluorochrome to another low molecular weight fluorochrome to form energy donor-acceptor complexes. Resonance energy transfer from an excited donor to fluorescent acceptor provides wavelength shifts up to 300 nm. The fluorescent labeling complexes preferably contain reactive groups for the labeling of functional groups on target compounds, such as derivatized oxy and deoxy polynucleic acids, antibodies, enzymes, proteins and other materials.

  • Patent number: 5901071
    Abstract: The composition of an alloy is inhomogeneous, so that the Fermi level of electrons in the surface of the alloy differs depending upon positions. It is accordingly considered that a part susceptible to corrosion and a part less susceptible thereto will coexist in the alloy. The corrosion rate of the alloy is indicated as the exponential function of a potential difference (.DELTA..PHI..sub.H) within an electric double layer. The potential difference remains unchanged as long as the Fermi level lies within the forbidden band of the electrons. However, in a range in which the Fermi level falls within the valence band of the electrons, the lowering thereof leads to the increase of the potential difference.

Charged (or even neutral) compounds present in the natural sample that bind to the added target molecule can alter its normal migration time upon CE, by changing its charge-to-mass ratio, or will cause a variation in peak shape or area. Complex formation can be detected by simply monitoring the migration of the target molecule during electrophoresis. Any new ligands that bind to the target molecule will be good candidates for therapeutic or diagnostic compounds. Interfering, weak-binding ligands commonly present in crude extracts are not detected.

  • Patent number: 5654198
    Abstract: Water-treatment compositions are provided which contain a water-soluble, water-treatment polymer and, optionally, additional water-treatment chemicals. The polymers are prepared from water-treatment monomers and a photo-inert, latently-detectable moiety which is covalently bonded to the polymer backbone. When the residue of the photo-inert moiety is contacted with an amount of a photoactivator which is effective to cause the residue of the photo-inert moiety to absorb within a wavelength ranging from 300 to 800 nanometers, the residue of the photo-inert moiety is detectable at concentrations of less than 100 parts per million. Methods are also provided which allow for the determination of the concentration of low levels, i.e., less than 100 ppm, of the water-treatment polymer present in an aqueous system.

  • Patent number: 5646216
    Abstract: A unitary plural-material, interocclusal dental appliance is disclosed for use in connection with orthodontic/orthopedic treatment of the teeth and jaws of a patient's mouth. The appliance includes a first region made from a first material that provides a relatively hard expanse with first and second surfaces, and with the second surface being contactable by one such set of teeth. The second surface may be constructed with a substantially planar shape, or with a shape conforming generally to the cusps of such one set of teeth. A second region is joined to the first region, and is made from a second material that provides a relatively soft, persistently resilient enclosure for the other such set of teeth. The second region includes plural zones, each of which is structured to allow an adjacent enclosed tooth to move toward the first surface of the first region, with such movement resulting in penetration of corresponding teeth into the relatively hard first material for a relatively precise distance.
