Abstract

Planar and 3D hydrogel scaffolds are patterned via direct-write assembly of hydrogel-based inks. Through simultaneous ink writing and UV polymerization, both 1D and 3D microperiodic scaffolds are created. 3T3 murine fibroblasts are seeded onto the scaffolds and their process development is observed using fluorescence microscopy.
