Abstract

The present invention relates to an amphiphilic polymer whose property and structure can change under hypoxic conditions, and to nanoparticles formed by self-assembly of the amphiphilic polymer. The hypoxia-responsive nanoparticles according to the present invention release a drug selectively under hypoxic conditions. Thus, the nanoparticles can be used for the selective diagnosis and treatment for diseases that are accompanied by hypoxia. Particularly, the nanoparticles can release a drug only to a targeted tumor in cancer therapy, and thus have minimized side effects and maximized therapeutic effects.
