Bioink composition is a key consideration for the 3D-bioprinting of complex and stable structures used to model tissues and as tissue constructs for regenerative medicine. An emerging and industrially important area of research is the use of micro- and nanofillers to improve bioink performance without dramatically altering the physicochemical properties of the polymeric material that forms the bulk of the printed structure. The purpose of this review is to provide a comprehensive overview of emerging nanomaterial fillers designed to create heterogeneous and composite bioinks for 3D-bioprinting of complex functional tissues. We outline the criteria that must be considered when developing such a bioink and discuss applications where the fillers impart stimuli responsiveness, e.g., when exposed to magnetic fields, electrical fields, and light. We further highlight how the use of such fillers can enable non-destructive imaging to monitor scaffold placement and integrity following implantation. |
