  • Publication number: 20240066182
    Abstract: The present disclosure provides a fiber membrane and a preparation method and use thereof, and belongs to the field of biological materials. The fiber membrane includes a fiber with a core-shell structure, where a core of the fiber includes simvastatin and a first spinnable polymer, and a shell of the fiber includes hydroxyapatite and a second spinnable polymer. In the fiber, a release of the simvastatin mainly depends on a rate of water invasion. After water invades the fiber, the simvastatin in the fiber leaves the fiber with the diffusion of water. In the present disclosure, a barrier function of the shell prevents moisture from entering the core. Therefore, the simvastatin in the core cannot leave the fiber with the diffusion of water molecules in an early stage, and a release rate of drugs is slowed down in the early stage, thereby controlling sustained release of the drugs.
