BIODEGRADABLE NANOPARTICLES

摘要

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.
