Entrapped nanofibers within hydrogel microparticles for cell encapsulation |
| 초록 |
Electrospun nanofiber based pH dependent microhydrogels were developed through a combination of normal electrospinning and spraying. In this study, we prepared the entrapped polystyrene (PS) nanofibers within sodium alginate (SA) microhydrogels through a combination of electrospinning and spraying and developed well defined microhydrogels with incorporated nanofibers. Optical microscopy revealed uniform surfaces and smooth structures (bead free) with SA microhydrogels entrapped PS nanofibers respectively. These physically sprayed SA microparticles were ionically crosslinked with aqueous calcium chloride. It concludes that 60 mins of ionic crosslink gives perfectly entrapped SA microhydrogels on the PS fibers. This work suggests one possible approach for drug release or cell encapsulation of such actives using microarchitectures. The combination of electrospinning and spraygun seems to be a useful technique for the preparation of microarchitectures and the combination of two nanomaterials. |
