제목 Micropatternednanofiber scaffolds for cell and protein microarrays
초록 We fabricated micropatterned polymeric nanofiber scaffolds that were capable of simultaneously generating cellular micropatterns within a biomimetic environment microdomains. To achieve this, we designed nanofiber scaffolds with both vertical and lateral microdomains. Vertically heterogeneous structures that were responsible for multi-functionality were realized by preparing double-layered nanofiber scaffolds consisting of an antibody-immobilized bottom layer of nanofibers and an upper layer of bare PS nanofibers by a two-step sequential electrospinning process. Photopatterning of PEG hydrogel on electrospun nanofibers produced heterogeneous micropatterned nanofiber scaffolds made of hydrogel microwells filled with a nanofibrous region, which is capable of generating cell and protein micropatterns due to the different interactions that cells and proteins have with PEG hydrogels and nanofibers.
