Nanoparticles for brain tumor imaging

摘要

Nanoparticle having a chitosan-polyethylene oxide oligomer copolymer coating, and methods for making and using the nanoparticle are provided. The nanoparticle can have a core that includes a material that imparts magnetic resonance imaging activity to the particle and, optionally, one or more of an associated targeting agent, fluorescent agent, or therapeutic agent.
