Patent number: 9938571Abstract: Manufacturing methods and compositions are described for production of self-contained microfluidic cartridge devices with on-board reagents for molecular biological testing. Sensitive reagents are stored in dry form without lyophilization or freezing, and reconstituted at the point of use with either a biological sample or a sample eluate at the point of use. Manufacturing methods include sheet and roll fabrication processes where the reagents are printed in place and sealed within individual microfluidic cartridges before gel vitrification.Type: GrantFiled: November 26, 2014Date of Patent: April 10, 2018Assignee: Micronics, Inc.Inventors: C. Frederick Battrell, Denise Maxine Hoekstra, Joan Haab, John R. Williford, Sabrina N. Gunderson, Elizabeth R. Leber, Isaac Sprague

Patent number: 9468894Abstract: Disclosed herein is a device comprising a pair of bellows pumps configured for efficient mixing at a microfluidic scale. By moving a fluid sample and particles in suspension through an aperture between the paired bellows pump mixing chambers, molecular collisions leading to binding between the particles and ligands in the sample are enhanced. Such devices provide an alternative for mixing that does not use a vent and can be used with a variety of particles in suspension such as magnetic beads to capture or purify useful cells and molecules.Type: GrantFiled: May 2, 2011Date of Patent: October 18, 2016Assignee: Micronics, Inc.Inventors: John Clemmens, C. Frederick Battrell, John Gerdes, Denise Maxine Hoekstra

Patent number: 8835146Abstract: Formulations for dry storage of PCR reagents are described. These formulations find use in manufacture of self-contained microfluidic card devices for PCR clinical testing in which the reagents are reconstituted at the point of testing. In these cards, TAQ polymerase is stored “on-board” in vitrified dry form without lyophilization or freezing, and is reconstituted by either the sample or a sample eluate during the assay.Type: GrantFiled: December 12, 2011Date of Patent: September 16, 2014Assignee: Micronics, Inc.Inventors: C.
