This invention relates to polymeric nanoparticles useful for drug delivery with target molecules bonded to the surface of the particles and having sizes of up to 1000 nm, preferably 1 nm to 400 nm, more preferably 1 nm to 200 nm, that are dispersed homogeneously in aqueous solution. The target drug/target substance is covalently bonded to the novel polymeric nanoparticles to secure them from outer intervention in vivo or cell culture in vitro until they are exposed at the target site within the cell. This invention also relates to microemulsion polymerization techniques useful for preparing the novel nanoparticles.
本发明涉及用于药物传递的聚合物纳米粒子,其表面结合有目标分子,其尺寸为最多1000纳米,优选为1纳米至400纳米,更优选为1纳米至200纳米,并在水溶液中均匀分散。目标药物/目标物质与新型聚合物纳米粒子共价结合,以确保它们在体内或体外细胞培养中受到外部干扰,直到它们在细胞内的目标位点暴露出来。本发明还涉及用于制备新型纳米粒子的微乳聚合技术。
