Reactive oxygen species (ROS)-responsive microspheres for targeted drug delivery of camptothecin

Non-selectivity of drugs used in the treatment of cancer inevitably leads to destruction of rapidly dividing normal healthy cells. In order to overcome this limitation a wide variety of targeted drug delivery systems have been reported. Among them, microparticulate drug delivery is a one of the most efficient routes and lacks responsiveness to external stimuli. In order to overcome this limitation a new drug delivery system based on reactive...
