  • Patent number: 12109317
    Abstract: Disclosed herein are electrospun fibrous matrix and its production method. The method mainly includes the steps of, mixing a first polymer and a drug to form a first mixture, and sonicating the first mixture until a plurality of microparticles are formed with the drug encapsulated therein; and mixing the plurality of microparticles with a second polymer to form a second mixture, subjecting the second mixture to a wet electrospinning process to form the electrospun fibrous matrix. The thus-produced electrospun fibrous matrix is characterized by having a plurality of first and second fibrils woven together, in which each second fibril has a plurality of drug-encapsulated microparticles independently integrated and disposed along the longitudinal direction of the second fibril. Also disclosed herein is a method for treating a wound of a subject. The method includes applying the present electrospun fibrous matrix to the wound of the subject.
