Résumé
The current prevalence of cancer chemotherapy drugs is inefficient and highly toxic, thus selecting the appropriate new forms of cancer treatment has become one of the important tasks. On the basis of domestic and foreign research literature, cutline the composition, characteristics and main preparation methods of polymeric micelles. Introduced varieties of stimuli-responsive polymer micelles, as well as targeted polymeric micelles used as an anticancer drug carrier. By making use of inside microenvironment of tumor cells, the preparation of various of new intelligent polymeric micelles with slight side effects and good treatment in virto and in vivo, can achieve effective control of drug release, which has great development and prospect in application.
