Redox‐Responsive Self‐Assembled Nanoparticles for Cancer Therapy

Abstract Chemotherapy, combined with other treatments, is widely applied in the clinical treatment of cancer. However, deficiencies inherited from the traditional route of administration limit its successful application. With the development of nanotechnology, a series of smart nanodelivery systems have been developed to utilize the unique tumor environment (pH changes, different enzymes, and redox potential gradients) and exogenous stimuli (thermal changes, magnetic fields, and light) to improve the curative effect of anticancer drugs. In this review, endogenous and exogenous stimuli are briefly introduced. Among these stimuli, various redox‐sensitive linkages are primarily described in detail, and their application with self‐assembled nanoparticles is recounted. Finally, the application of redox‐responsive self‐assembled nanoparticles in cancer therapy is summarized.
