The present invention relates to polymeric nanoparticles useful in drug and agent delivery, as well as for imaging, diagnosis and targeting. The polymeric nanoparticles of the present invention comprise polymers and cross-linkers that, when degraded, leave simple nontoxic biocompatible molecules that can be metabolized, excreted, or absorbed by the body. The present invention also relates to processes for producing the polymeric nanoparticles of the present invention, and methods of using them in drug and agent delivery, as well as imaging, diagnosis and targeting.
本发明涉及在药物和药剂传递中有用的高分子纳米粒子,以及用于成像、诊断和靶向的高分子纳米粒子。本发明的高分子纳米粒子包括聚合物和交联剂,当其降解时,会留下简单的无毒生物相容分子,可以被身体代谢、排泄或吸收。本发明还涉及制备本发明的高分子纳米粒子的过程,以及在药物和药剂传递、成像、诊断和靶向中使用它们的方法。
