Patent number: 11181105Abstract: Microfluidic circuit elements, such as a microvalve, micropump or microvent, formed of a microcavity divided by a diaphragm web into a first subcavity bounded by a first internal wall and a second subcavity bounded by a second internal wall, where the diaphragm web is characterized as a thin film having a first state contacting the first internal wall and a second state contacting the second internal wall and exhibiting essentially no elasticity in moving between the first state and the second state, the thin film web having been stretched beyond its yield point before or during use are provided. The disclosed elements enable faster and more efficient cycling of the diaphragm in the microcavity and increases the diaphragm surface area. In a preferred embodiment, the microfluidic circuit element is pneumatically driven and controls the motion of fluids in a microassay device.Type: GrantFiled: November 8, 2019Date of Patent: November 23, 2021Assignee: PERKINELMER HEALTH SCIENCES, INC.Inventors: Isaac Sprague, Justin L. Kay, Matthew Scott Bragd, C. Frederick Battrell

Publication number: 20170113221Abstract: Disclosed is a microassay testing system, including a microfluidic cartridge and a compact microprocessor-controlled instrument for fluorometric assays in liquid samples, the cartridge having integrated process controls and positive and negative assay controls. The instrument has a scanning detector head incorporating multiple optical channels. In a preferred configuration, the assay is validated using dual channel optics for monitoring a first fluorophore associated with a target analyte and a second fluorophore associated with a process control. Integrated positive and negative assay controls provide enhanced assay validation capabilities and facilitate analysis of test results. Applications include molecular biological assays based on PCR amplification of target nucleic acids and fluorometric assays in general.Type: ApplicationFiled: June 11, 2015Publication date: April 27, 2017Inventors: Danny Hoffman, Asa Bergdahl, Megan Couch, Raf Rivera, Matthew Scott Bragd, Alan K. Lofquist, Andrew Kolb, Justin L. Kay
