제목 Photoactive cellulose nanofiber hydrogel
초록 The crosslinking of cellulose nanofiber (CNF) provides a variety of potential applications with environmental and biological 3D structures. Despite their good physical properties, they have been excluded from the field of photo-crosslinking because of the lack of active sites for lights. In this presentation, we demonstrate the introduction of a chemically active site to CNFs to form dityrosine bondings. The photoactive gelation of CNF suspension verifies the reactivity of CNF derivatives and enables the 3D structuring of CNF-based ink, which will be applicable for the fabrication of bioactive platforms in the future. A variety of CNF structures can be printed by DIW mode followed by light induced gelation.
