제목 FABRICATION OF HYALURONAN-BASE NANOFIBRILS BY COAXIAL ELECTROSPINNING
초록 For several reasons, the electrospinning of nanofibrous mats comprised of biopolymers, such as hyaluronic acid (HA) has been difficult to achieve. In this study, HA-based nanofibers were fabricated via coaxial electrospinning with poly(ɛ-caprolactone) (PCL) as sheath and methacrylated HA as core. After photocrosslinking, the nanofibers were hydrolyzed into nanofibrils (NFs). The PCL sheath was then removed to obtain HA NFs. The methacrylation of HA was confirmed by 1H NMR. Morphology of nanofibers was evaluated by scanning electron microscopy (SEM) and the sheath/core structure of nanofibers was confirmed by transmission electron microscopy (TEM). Swelling behavior and biodegradability was also determined. Furthermore, the formation of NFs/cell complexes and the proliferation of cells were investigated.
