Application

Peptide bioink is optimized for bioprinting applications and can be printed with great fidelity to create a self-supporting 3D scaffold. This bioink has been designed to work easily and accurately with both extrusion-based and ink-jet printers to produce high-quality and reliable prints. Peptide bioink is based on self-assembling peptide hydrogel technology. The resulting hydrogel is a nanofibrous network with a similar nanoscale matrix structure to that of the native extracellular matrix (ECM) in human tissue. This bioink prints without the need for temperature or pH adjustment, UV curing, or addition of reactive cross-linking reagents, all of which can be detrimental to the health of cells. The gelation is triggered by the addition of cell culture media.

The product is provided as a lyophilized peptide bioink powder and a preparation solution, which allows formulation of gels with different stiffness and rigidity that can emulate specific physical properties of a wide range of different tissue types.

Printable scaffolds with adequate mechanical strength and stiffness are sought after to ensure viability of printed cells and tissues. We report the first peptide bioinks-lysine-containing hexapeptides that self-assemble into stable, nanofibrous three-dimensional hydrogels with unprecedented stiffness of up to 40
