Abstract
We have developed an in situ bioprinting method that allows printing of cells under true physiological conditions applying self-assembling ultrashort peptides as bioinks. This method avoids cell stressing methods such as UV-treatment, chemical crosslinking and viscous bioinks printing methods. We further demonstrate that different nanomaterials can easily be synthesized or incorporated in the 3D bioprinted peptide scaffolds which open up the possibility of functionalized 3D scaffolds.
