Patent number: 11974982Abstract: Compositions comprising an active oxygen-responsive antioxidant crystal, methods of making them, and methods for controlling the dissolution rate and/or altering the crystallization behavior of an antioxidant are disclosed. The crystals comprise an antioxidant and a disulfide- or diselenide-crosslinked polymer that is adsorbed onto a surface of the antioxidant. Upon exposure to an active-oxygen stimulus, the polymer de-crosslinks to release the antioxidant from the composition in an amount effective to counteract the stimulus. While prior approaches to altering dissolution rates have relied on passive zero- or first-order kinetics that are independent of ROS levels, the inventive compositions actively respond by releasing antioxidant in an amount proportional to the concentration of active-oxygen species present. The crystallization methods are simple and scalable.Type: GrantFiled: March 30, 2021Date of Patent: May 7, 2024Assignee: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOISInventors: Hyunjoon Kong, Byoungsoo Kim, Jonghwi Lee, Youngjun Kim, Ryan Cree Miller
