The characteristics distinction between bioink and biomaterial ink. In a bioink, cells are the mandatory component of the printing formulation, which can be in the form of single cells, coated cells and cell aggregates (one or several type of cells). The bioink may contain biomaterials and biologically active components. Meanwhile, the biomaterial ink is where the seeding cells are introduced within biomaterial scaffolds after printing.
