  • Patent number: 11535795
    Abstract: Methods are disclosed to restore the halide ions lost in the purification (ligand removal) of photoluminescent cesium lead halide or FA lead halide perovskite quantum dots. Quantum dots thus prepared can be used to deposit solid films with high packing density featuring dots with <0.4 nm gaps therebetween, low trap density 1/40 of previously reported, high mobility 100× previously reported, high photoluminescent quantum yield exceeding 90%, high external quantum yield exceeding 20%, and increased stability under electrical current. The quantum dots are used to formulate inks suitable for ink jet printing, drop casting, spin coating, and other solution-based methods for forming emissive layers used in light producing semiconductor devices.

  • Patent number: 8501495
    Abstract: A sequential solid phase immunoassay and system is disclosed. The immunoassay utilizes the secondary antibody method for the detection of antibodies in a membrane-based test. The system comprises a test strip including a nitrocellulose membrane having an immobilized antigen in a capture zone on the membrane and a stabilized liquid secondary antibody conjugate. The sequential solid phase immunoassay is performed in a sequential manner with the addition of a fluid specimen being followed by the addition of the stabilized liquid secondary antibody conjugate. The sequential procedure using the system includes allowing the fluid specimen containing antibodies specific to the antigen to pass laterally from the test strip first end through the capture zone. The immobilized antigens in the capture zone capture antibodies specific to the antigen. The stabilized liquid secondary antibody conjugate then binds to the captured antibodies and can be detected visually or by a machine or reader.

  • Patent number: 5420013
    Abstract: Methods and compositions are provided for detecting HLA polymorphs where distinguishing antibodies are not readily available. Cross-reactive antibodies are employed, where one cross-reacts with the HLA of interest and other alleles, and the other cross-reacts with one of the other alleles, but not with the HLA of interest. By appropriate protocols and controls, the polymorph of interest may be detected.
