摘要： The present disclosed a preparation method preparation method for, and use of, a small molecular drug-loaded polymer vesicle. The small molecular drug-loaded polymer vesicle is prepared by assembling an amphiphilic block polymer and a small molecular drug; or is obtained by assembling and cross-linking the amphiphilic block polymer and a functionalized amphiphilic block polymer, loading the small molecular drug, and then reacting with a targeting monoclonal antibody. The vesicle system has many unique advantages, including small size, simple and controllable preparation, excellent biocompatibility, high stability of circulation in vivo, strong specific selectivity of tumor cells, high intracellular drug release rate, remarkable effect of tumor growth inhibition, etc. Therefore, the vesicle system is expected to become a simple and multi-functional nano-platform for efficient and specific targeted delivery of vincristine sulfate to multiple myeloma cells.
