Hollow fibers are a type of chemical fiber material with a linear tube like cavity.The membrane wall is densely packed with micropores,which can intercept macromolecular substances and serve as a carrier for cell growth.They are widely used in the field of pharmaceutical science,including screening of active ingredients in natural drugs,sample pretreatment,microextraction,construction of pharmacokinetic and pharmacodynamic models.This paper elaborates the current application status of hollow fibers,which provides a reference for further exploration of the application in the pharmaceutical field.
