  • Publication number: 20230201129
    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 encompassed in the present disclosure 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 to accelerate wound healing.

  • Patent number: 9132574
    Abstract: Disclosed are a substrate with a microstructure and a method for producing the same. In this method microparticles of a random allocation by means of a natural self-assembly mechanism are used to coat on a master mold. Firstly, hollow micro glass particles within a specific size range are mixed with a UV-curable adhesive to become a mixed solution. Afterwards, the master mold is dip-coated in the mixed solution and the microparticles coated on the master mold are self-assembled. To fix the microparticles on the master mold to form a sphere array microstructure with a three dimensional random allocation, a UV light source is used to radiate the master mold for curing. Afterwards, an inverse mold with the corresponding microstructure is fabricated by electroforming or polydimethylsiloxane (PDMS) casting the master mold. Thus, the inverse mold can be applied to the fabrication of a substrate with the corresponding microstructure.
