The composition finds utility as a tooth whitening composition and is applied to the teeth in need of whitening, and then removed when the degree of whitening has been achieved. In certain embodiments, the composition is translucent. Methods for preparing and using the compositions are also disclosed.
专利号:US-2003138490-A1 优先权日:2001-09-08 标 题 :Synthesis and uses of polymer gel nanoparticle networks 发明人:HU ZHIBING; LU XIHUA; GAO JUN; PONDER BILL C; JOHN JOHN ST; MORO DANIEL G 摘要:Disclosed is a new class of nanostructured polymeric materials comprising polymer gel nanoparticles that are covalently bonded through functional groups on the surfaces of neighboring particles. These nanoparticles may be prepared as suspensions in an aqueous or, non-aqueous environment. These gels have two unique and different structural networks; the primary network comprises crosslinked polymer chains in each individual particle, while the secondary network is a system of crosslinked nanoparticles. Particular polymer gel nanoparticle network compositions disclosed herein may function as carriers for controlled delivery of pharmaceuticals or other chemical agents, gel sensors and other commercial applications.

专利号:US-7993390-B2 优先权日:2002-02-08 标 题:Implantable or insertable medical device resistant to microbial growth and biofilm formation 发明人:MILLER KATHLEEN M; BUCAY-COUTO WEENNA; LI JIANMIN 权利人:BOSTON SCIENT SCIMED INC 摘要:Disclosed are implantable or insertable medical devices that provide resistance to microbial growth on and in the environment of the device and resistance to microbial adhesion and biofilm formation on the device. In particular, the invention discloses implantable or insertable medical devices that comprise at least one biocompatible matrix polymer region, an antimicrobial agent for providing resistance to microbial growth and/or a microbial adhesion/biofilm synthesis inhibitor for inhibiting the attachment of microbes and the synthesis and accumulation of biofilm on the surface of the medical device. Also disclosed are methods of manufacturing such devices under conditions that substantially prevent preferential partitioning of any of said bioactive agents to a surface of the biocompatible matrix polymer and substantially prevent chemical modification of said bioactive agents.
