  • Multimode degradable hydrogels for controlled release of cargo substances
    Patent number: 10172938
    Abstract: A responsive hydrogel-based material may be used as a carrier system for the in situ delivery of various cargo substances, including bioactive moieties. The hydrogel structure, which includes photodegradable and thioether moieties in its three dimensional network, enables finely tuned local release of cargo substances as a function of the in vivo tissue environment (e.g., enzyme concentration or reducing environment) and externally applied stimuli (e.g., light) by selective spatiotemporal hydrogel degradation.
    Type: Grant
    Filed: April 28, 2015
    Date of Patent: January 8, 2019
    Assignees: University of Delaware, The Regents of the University of California
    Inventors: Kristi L. Kiick, April M. Kloxin, Prathamesh M. Kharkar, Raja Sivamani, Emanual Maverakis
