  • Modification of segmented polyurethane properties by copolymerizing with pendant functionalized diols
    Patent number: 11116211
    Abstract: A functionalized polyurethane polymer is provided, the polymer defined by the formula where each R? is independently derived from a diisocyanate, where each R? represents the soft segment of the polymer, where n is the number of repeat units within the soft segment of the polymer, where m is the number of repeating mer units in the polymer, where each E is a pendant-functionalized amide unit chain extender, wherein the nitrogen atom of the amide group is part of the polymer backbone. A method for preparing the polymer is also provided.
    Type: Grant
    Filed: June 12, 2019
    Date of Patent: September 14, 2021
    Assignee: The University of Akron
    Inventors: Abraham Joy, Chao Peng, Zhuoran Li, Nicholas Nun, Apoorva Vishwakarma
  • Photodegradable sample collection system and method
    Patent number: 10598577
    Abstract: A method includes providing a biological sample, providing a sample collection device, wherein the sample collection device includes a sample binding surface including a photodegradable polymer configured to bind the biological sample, contacting the biological sample with the sample binding surface of the sample collection device, and irradiating the sample binding surface and the bound biological sample using light emitted from a light source to initiate degradation of the photodegradable polymer of the sample binding surface to cause release of the biological sample.
