Patent number: 11918695Abstract: Core-shell particles have a hydrophobic core and a shell formed of o containing hyperbranched polymers (HP). The HP can be covalently bound to the one or more materials that form the core or coated thereon. The HP coating can be modified to adjust the properties of the particles. For example, unmodified HP coatings resist non-specific protein absorption. Alternatively, the hydroxyl groups on the HP coating can be chemically modified to form functional groups that react with functional groups on tissue to adhere the particles to the tissue, cells, or extracellular materials, such as proteins. Such functional groups include, but not limited to, aldehydes, amines, and O-substituted oximes. Topical formulation for application to the skin contain these HP coated nanoparticles. In some embodiments, the particles include cosmetic, therapeutic, diagnostic, nutraceutical, and/or prophylactic agents, such as those used as sunblock compositions.Type: GrantFiled: May 11, 2016Date of Patent: March 5, 2024Assignee: YALE UNIVERSITYInventors: Yang Deng, Asiri Ediriwickrema, William M. Saltzman, Michael Girardi

Patent number: 11896686Abstract: Core-shell particles and methods of making and using thereof are described herein. The core is formed of or contains one or more hydrophobic materials or more hydrophobic materials. The shell is formed of or contains hyperbranched polyglycerol (HPG). The HPG coating can be modified to adjust the properties of the particles. Unmodified HPG coatings impart stealth properties to the particles which resist non-specific protein absorption and increase circulation in the blood. The hydroxyl groups on the HPG coating can be chemically modified to form functional groups that react with functional groups and adhere the particles to tissue, cells, or extracellular materials, such as proteins.Type: GrantFiled: June 16, 2022Date of Patent: February 13, 2024Assignee: YALE UNIVERSITYInventors: Yang Deng, Asiri Ediriwickrema, William M.
