Patent number: 11433396Abstract: In a polymer assay cartridge having wells containing reagents, beads and sample, where the wells are covered (e.g., with Parafilm® or films) and shipped to the point of care, the reagents and well contents can leak out. The reagent solutions are made semi-solid by adding hydrogel reagents and cooling to form a gel. Preferably, the hydrogel is heated before an assay is conducted with the cartridge, and pigmented beads in the wells indicate melting or excessive heating, or congealing of the hydrogel, based on pigment color change.Type: GrantFiled: August 5, 2020Date of Patent: September 6, 2022Assignee: Fannin Partners LLCInventors: Leo Linbeck, III, Dev Chatterjee, Michael John Heffernan

Patent number: 11327087Abstract: The invention herein relates to conducting assays with an apparatus including a substantially transparent assay cartridge loaded with magnetic beads, and a magnets positioned in a platform above and below the assay cartridge. The assay cartridge includes magnetic beads, sample and control solutions in some wells, and assay reagents in others. A microcomputer controls a linear actuator which moves the magnet platform causing the magnetic beads to travel from one well to another and to oscillate within a well. At assay completion, the cartridge will generate a signal representing a test result, which is then sent to a server through a wireless transmission system.Type: GrantFiled: April 13, 2020Date of Patent: May 10, 2022Assignee: BREVITEST TECHNOLOGIES, LLCInventors: Leo Linbeck, III, Javier Trinidad Garza, Jr., Robert Patrick Garr, Dev Chatterjee

Patent number: 10828636Abstract: The invention relates to conducting assays with an apparatus including a substantially transparent assay cartridge loaded with magnetic beads, and a magnet carrier base positioned below a scanning platform holding the assay cartridge. A microcomputer controls a stepping motor which controls movement of the magnet carrier base, and causes the magnetic beads to travel from one well to another, where the wells contain different assay reagents. An electromagnetic coil-spring assembly induces mixing of well contents with the magnetic beads on actuation. The assay cartridge is authenticated by sending its encoded identifier to a server or website, and assay instructions are provided remotely to the microcomputer. Following assay completion, the cartridge can have color change or other assay indication detected, and the results sent to the server or website or another recipient. Concurrently assaying a control allows modification of assay results based on measured field conditions.Type: GrantFiled: October 25, 2017Date of Patent: November 10, 2020Assignee: FANNIN PARTNERS LLCInventors: Leo Linbeck, III, Michael John Heffernan, Dev Chatterjee, Atul Varadhachary

Patent number: 9528985Abstract: Disclosed herein are systems and methods for using the controlled movement of magnetic particles using controlled magnetic fields in a fluidic device containing separated fluidic regions to detect analytes in solution by immunoassay, such as an enzyme-linked immunosorbant assay (ELISA) for various medical and scientific applications. In order to achieve sequential exposure to the different chemical environments required in an immunoassay, magnetic particles are driven through fluid-containing chambers separated by air-gaps that may take the form of air bubbles or small open-air separations, for example. Externally controlled magnets coupled to actuators draw the flow of magnetic particles through air-liquid interfaces produced by microfluidic surface tension at the air-gap, washing the particles.Type: GrantFiled: January 11, 2016Date of Patent: December 27, 2016Assignee: FANNIN INNOVATION STUDIO, INC.Inventors: Dev Chatterjee, Atul Varadhachary, Leo Linbeck, III
