发明名称 METHOD FOR PRODUCING A SILK NANOFIBER NERVE CONDUIT
摘要 The present invention relates to a silk nanofiber nerve conduit characterized in that fibroin nanofibers having a diameter of 200 to 400 nm, originated from silk fiber, are stacked layer upon layer to form a porous conduit-shape; and a method for producing thereof, more specifically, to a method for producing a silk nanofiber nerve conduit comprising: (Step 1) preparing a fibrous spinning solution; (Step 2) producing a silk nanofiber of conduit-shape by electrospinning the fibrous spinning solution prepared in step 1 into the cylindrical collecting part coated with polyethyleneoxide; and (Step 3) separating a silk nanofiber of conduit-shape produced in step 2 from the collecting part. The silk nanofiber nerve conduit of the present invention has excellent biocompatibility; allows the body fluid to be exchanged inter in and out of conduit through pores of the conduit, as well; has a proper elasticity, tensile strength, and tear strength. Due to these properties, the silk nanofiber nerve conduit of the present invention helps the regeneration of the nerve injury to recover a motor skill and a sensory function, and thus shows an excellent effect of nerve regeneration. Therefore, the silk nanofiber nerve conduit of the present invention can be used in treating a nerve injury instead of an existing synthetic polymeric nerve conduit.
