The nanofibers prepared by electrospinning have a porous structure and a large specific surface area. They are widely used in protective clothing

filter membrane

wound dressing and other fields. With the advancement in the medical field

the nanofibers prepared by electrospinning have become increasingly prominent as drug carriers. The drugs in the nanofibers can be released effectively and continuously by different drug-loaded methods. Therefore

the nanofiber is considered as one of the ideal materials in the field of drug release and tissue engineering. In this paper

the principle of electrospinning and the research progress of electrospinning in the field of cont:J.·olled山ug release are mainly discussed. It provides a theoretical basis for the modification and application of controlled drug release fibers in future.
