Applications of Nano-drugs and Tumor Microenvironment Sensitive Nano-drug Delivery Systems

Cancer therapy is an attractive research field in basic and clinical studies. Among them, nano-based antitumor drugs and delivery systems play increasingly crucial role in tumor treatment, while they are still faced with complicated surrounding environments. Therefore, this review summarized the tumor micro-environments and some nano-based delivery systems including some FDA-approved nano-drugs for clinical use, in addition, the tumor microenvironment sensitive drug delivery systems are also illustrated.
