Patent number: 8877227Abstract: The present invention relates to reversible hydrogel systems. Particularly, the hydrogel of the present invention is made up of copolymers that can be a hydrogel when in an oxidized state and can be a solution when in a reduced state. A solution of the copolymer can be oxidized to form a hydrogel; and the hydrogel can be reduced to form a solution of the copolymer. Reversible nanogels can also be formed from a dilute solution of the copolymers. The hydrogel is formed with nanoparticles embedded therein to form a nanocomposite whose refractive index and modulus can be controlled by varying the amounts of nanoparticles and the polymer concentration of the hydrogel, respectively.Type: GrantFiled: February 2, 2011Date of Patent: November 4, 2014Assignee: The United States of America, as represented by the Department of Veterans AffairsInventor: Nathan Ravi

Patent number: 8192485Abstract: The present invention relates to reversible hydrogel systems for medical applications. Particularly, the hydrogel of the present invention is made up of copolymers that can be a hydrogel when in an oxidized state and can be a solution when in a reduced state. A solution of the copolymer can be oxidized to form a hydrogel; and the hydrogel can be reduced to form a solution of the copolymer. The solution can be dehydrated to produce the dry copolymer for storage. Furthermore, the present invention also relates to methods of making and using the reversible hydrogel systems.Type: GrantFiled: November 13, 2003Date of Patent: June 5, 2012Assignees: The United States of America, as represented by the Department of Veterens Affairs, The Washington University in St. LouisInventor: Nathan Ravi
