Bioinks are the interface between a bioprinter and biological cells. The printability, shape fidelity and cell viability form the basic requirements of bioinks development. Adjustment of compositions has also been constantly explored to modulate certain properties of bioinks. However, to further advance beyond these basics, bioinks involving new chemistry or new physics capable of delivering multi-functions for in vivo performance should be designed, synthesized, and tested. Novel derivatives and new material classes would help unveil the mystery of the interface between living and non-living materials. This column aims to collect the on-going research focuses on bioinks innovation and reveal the current thinking of future bioinks.
