  • 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
