Core-Sheath Nanofibers consisting ofPolymericshell andFunctional colloids in the core for Programmable Delivery |
| 초록 |
Polymeric nanofibers have been attracting significant attention lately for topical drug delivery applications. The ever growing interest on nanofibers are based on their ability to incorporate a wide range of drugs, the high surface area of the 3D mats for efficient drug release and the ease of fabricating the delivery vehicle in the required architecture. The nanofibers are considered to be useful for wound dressing, artificial organs and multifunctional membranes. Electrospinning system is a useful way to fabricate nanofibers in a continuous process. The dimension of the nanofibers can be controlled from tens of nanometers to a few micrometers. We fabricated core-sheath nanofibers consisting of PCL shell and hydrogel core by using electrospinning method. Core-shell structured nanofibers have crosslinked PMMA colloids & PNIPAm hydrogel colloids distributed in its core and polymer on its shell. We observed that dye of nanofibers released during experimental period. |
