  • Hydrogel membrane and methods for selective retrieval of microbial targets
    Patent number: 11235330
    Abstract: Polymer hydrogels and methods for selective retrieval of microbial targets from microwells and other cell culture devices. The methods use semi-permeable, photodegradable hydrogel membranes that permit exchange of nutrients and waste products but seals motile bacteria and other microbes within microwells. Light exposure can be used to degrade the hydrogel membrane in a targeted manner and release the microbes from targeted microwells for further study.
    Type: Grant
    Filed: October 5, 2018
    Date of Patent: February 1, 2022
    Assignee: Kansas State University Research Foundation
    Inventors: Ryan R. Hansen, Thomas G. Platt, Andre Jacobus van der Vlies

  • Microfluidic flow assay for measuring hemostatic phenotypes
    Patent number: 8486349
    Abstract: A microfluidic-based flow assay and methods of manufacturing the same are provided. Specifically, the microfluidic flow assay includes a micropatterned surface that induces clot formation and an array of microfluidic channels though which blood flows. The micropatterned surface contains two clotting stimuli, one for inducing platelet adhesion and another for inducing the coagulation cascade.
