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.
本发明涉及一种在缺氧条件下其性质和结构可以改变的两性聚合物,以及由这种两性聚合物自组装形成的纳米粒子。根据本发明的缺氧响应性纳米粒子在缺氧条件下选择性地释放药物。因此,这些纳米粒子可用于对伴随缺氧的疾病进行选择性诊断和治疗。特别是,这些纳米粒子可以在癌症治疗中仅向靶向肿瘤释放药物,从而最大程度地减少副作用并最大化治疗效果。
