Publication number: 20170202874Abstract: Multivalent scaffolds configured to facilitate drug release upon exposure to a stimulus, such as heat, or light, are described herein. The multivalent scaffolds are covalently bound to a moiety that is susceptible to decomposition upon exposure to stimulus. The moiety releases HNO upon decomposition. In some embodiments, the moiety is in turn linked to an agent to be delivered, such as a therapeutic agent, which is released from the multivalent scaffolds when the moiety decomposes. In some embodiments, the moiety is a 1,2-oxazine moiety. In some embodiments, the multivalent scaffold is a polymer. A plurality of 1,2-oxazine moieties can be covalently bound as side chains to the backbone of the polymer.Type: ApplicationFiled: January 13, 2017Publication date: July 20, 2017Applicants: University of Washington, Pacific Lutheran UniversityInventors: Andrew J. Boydston, Neal A. Yakelis, Derek C. Church

Patent number: 9695280Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles of polymer materials using 3D printing. A syringe or an inkjet print head prints a solution of prepolymer onto a build plate. The printed prepolymer is exposed to a stimulus whereby the prepolymer is converted to the polymer. After a predetermined time, sequential layers are printed to provide the three-dimensional article. The three-dimensional article can be cured to produce the 3D article made from the final polymer.Type: GrantFiled: January 8, 2016Date of Patent: July 4, 2017Assignees: Ricoh Co., Ltd., University of WashingtonInventors: Andrew J. Boydston, Mark A. Ganter, Duane Storti, Adam Edward Goetz, Mete Yurtoglu, Michael Byrnes Larsen, Gregory Isaac Peterson, Di Zhang

Patent number: 9580553Abstract: A polymer including a self-immolative polymer segment and a thermally-activated trigger moiety is described. The self-immolative polymer segment includes a head end, a tail end, and a plurality of repeating units. The trigger moiety includes a cycloaddition adduct that is covalently coupled to the head end of the self-immolative polymer segment. When the polymer is exposed to an activation temperature, the cycloaddition adduct undergoes retro-cycloaddition to release the self-immolative polymer segment. The self-immolative polymer segment then decomposes to sequentially release repeating units in a head-to-tail direction.Type: GrantFiled: December 9, 2013Date of Patent: February 28, 2017Assignees: University of Washington through its Center for Commercialization, Pacific Lutheran UniversityInventors: Andrew J. Boydston, Neal A. Yakelis, Ronald Jay Berenson, Derek C. Church, Gregory I. Peterson, Michael Larsen

Publication number: 20160257843Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. The deposited powder bed is heated to about 50° C. to about 170° C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.Type: ApplicationFiled: January 8, 2016Publication date: September 8, 2016Applicants: Ricoh Co., Ltd., University of WashingtonInventors: Andrew J.

Patent number: 8933143Abstract: Compositions and methods for adjustable lenses are provided. In some embodiments, the lenses contain a lens matrix material, a masking compound, and a prepolymer. The lens matrix material provides structure to the lens. The masking compound is capable of blocking polymerization or crosslinking of the prepolymer, until photoisomerization of the compound is triggered, and the compound is converted from a first isomer to a second isomer having a different absorption profile. The prepolymer is a composition that can undergo a polymerization or crosslinking reaction upon photoinitiation to alter one or more of the properties of the lenses.Type: GrantFiled: November 5, 2013Date of Patent: January 13, 2015Assignee: California Institute of TechnologyInventors: Andrew J.
