Application of responsive nano-drug delivery system in cancer therapy

In recent years, responsive nano-drug delivery systems have been extensively studied for cancer therapy due to their enhanced permeability and retention effect. In this review, we discuss recent advances in the development of responsive nano-drug delivery systems that are able to control drug biodistribution in response to specific stimuli, either exogenous (variations in temperature, magnetic field or light) or endogenous (changes in pH or enzyme concentration).
