The maintenance of a high delivery efficiency by traditional nanomedicines during cancer treatment is a challenging task.As a natural mediator for short-distance intercellular communication, extracellular vesicles (EVs) have garnered significant attention owing to aptamil allerpro their low immunogenicity and high targeting ability.They can load a variety of major drugs, thus offering immense potential.In order to overcome the limitations of EVs and establish them as an ideal drug delivery system, polymer-engineered extracellular vesicle mimics (EVMs) have been developed and applied in cancer therapy.In this review, we discuss the current status of polymer-based extracellular vesicle mimics in drug delivery, and analyze their structural and functional properties based on the design of drosselklappe stellantrieb an ideal drug copyright.
We anticipate that this review will facilitate a deeper understanding of the extracellular vesicular mimetic drug delivery system, and stimulate the progress and advancement of this field.
