摘要： A method for generating a cell support interface for use in a three dimensional cell culture environment, may include electrospinning a mat having an epithelial support layer configured to create an intimate coupling between the epithelial cell and a porous matrix, including a first layer and a second layer, wherein the first layer is formed using a first solution at a first viscosity level and the second layer is formed using a second solution at a second viscosity level different from the first viscosity level.

摘要： Disclosed herein is the production of medical textile material with nanofiber surface that has transdermal drug release properties and that is coated with azithromycin active substance by using needle electrospinning method and ultrasonic spray pyrolysis (USP) technique. Specifically disclosed is a nanofiber medical textile material production method that includes the steps of preparing polymer solutions containing PVP (polyvinylpyrrolidone) with a concentration of 12 wt % and GEL (gelatin) with a concentration of 0.72 wt %; determining solution properties such as conductivity, viscosity, and surface tension, producing nanofibers from prepared polymer solutions by atmosphere-controlled horizontal needle fiber spinning (electrospinning) setup, obtaining PVP/GEL nanofibers after the fiber spinning process, thin film coating of the drug active substance on the obtained nanofibers, PVP/GEL nanofibers by the USP method, and cross-linking of both polymers to facilitate the final application processes of the drug-release material.
