  • Patent number: 10871486
    Abstract: Devices and methods for performing a point of care diagnostic test for detecting and quantifying at least one analyte in a biological sample. The device may include an immunoassay apparatus and a holder with a variable angle stage for positioning the immunoassay apparatus relative to a light source and a detector device. In one embodiment, the device is based upon elastic light scattering, so the variation in the angle of incidence and angle of reflection are optimized to maximize signal generation due to elastic light scattering. The detector device may include a wired or wireless connection to a computer network for communicating with an electronic medical records system, uploading the amount or concentration of at least one analyte present in the sample to the electronic medical records system, or querying a decision support algorithm stored in a computer readable format. The detector device may further include an onboard interpretive algorithm.

  • Patent number: 9719134
    Abstract: Disclosed herein are automated systems for performing various biochemical and molecular biological procedures, including processor-controlled execution of protocols involving multiple steps performed in, on, or with liquid microdroplets. Example protocols are the various Polymerase Chain Reaction (PCR) protocols, but the subject systems are not limited to performing PCR protocols. Formation of a microdroplet of the sample for use in the described systems is achieved by bringing an amount of the sample into contact with a hydrophobic milieu, such as a superhydrophobic surface or hydrophobic liquid.

  • Patent number: 9678005
    Abstract: The present invention features methods and devices for microorganisms through detecting Mie light scattering from immunoagglutinated beads. The methods feature providing a first bead suspension with antibody specific for the microorganism conjugated to beads; mixing the first bead suspension with a sample to form a first mixture; irradiating the first mixture with first incident light; detecting forward light scattering at a first angle with respect to the first incident light, where the first angle being between about 30 to 60 degrees; determining I from the light scattering; providing a second bead suspension with no antibody and simultaneously measuring I0 in a similar manner; comparing I with I0. All light scattering measurements may be made in a two-well slide or a Y-channel microfluidic device.

  • Patent number: 9562855
    Abstract: Microfluidic methods and systems for detecting levels of microorganisms via Mie forward light scattering. The systems and methods of the present invention can be customized so as to optionally maximize scatter from the particle immunoagglutination and minimize that of the sample matrix, e.g., via selection of parameters particle diameter d, wavelength of incident ?, and/or scatter angle ?. Methods feature providing beads conjugated with an antibody specific for the microorganism, mixing beads with a sample to form a first mixture; providing a control mixture; irradiating the mixtures with incident light; detecting forward light scattering scattered by the first mixture at a first angle with respect to the incident light and forward scattered light scattered by the control the same first angle with respect to the incident light; determining I and I0 from the light scattering; comparing I with I0; and determining a level of the microorganism.

  • Patent number: 8889424
    Abstract: A device and method for performing a point of care diagnostic test for detecting and quantifying at least one analyte in a biological sample (e.g., a body fluid). A device may include an immunoassay apparatus and a holder with an adjustable variable angle stage for positioning the immunoassay apparatus relative to a light source and a detector device so as to optimize the angle of incidence and angle of radiation to optimize an elastic light scattering signal from the immunoassay apparatus. The elastic light scattering signal may be used to quantify the amount of the analyte(s) of interest present in the sample. The device is based upon elastic light scattering, so the variation in the angle of incidence and angle of reflection are optimized to maximize signal generation due to elastic light scattering.
