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.

摘要:A protein effective in stimulating cell growth activity. The protein has a molecular weight of from 5,000 to about 160,000, is composed predominantly of neutral and acidic amino acids, contains a significant amount of glutamic acid and aspartic acid, and is substantially free of nucleoside phosphotransferase. The protein is useful as wound treatment agent and as promoting agent in the synthesis of DNA. A method of producing the protein and compositions containing the same are also disclosed.
