Bioink viscosity

WebJul 21, 2024 · The shear stress that the cells experience is a direct function of bioink viscosity and the printing speed and is inversely related to the nozzle diameter. Therefore, any efforts to increase the printing speed and resolution may expose cells to high shear stresses and reduced cell viability. Although reducing bioink viscosity improves cell ... WebThe high viscosity of fibrin (crosslinked form) hinders proper ink extrusion, and its pre-polymer form, fibrinogen, is not capable of maintaining shape fidelity. To overcome these limitations and empower fibrinogen-based bioinks for fibrin biomimetics and regenerative applications, different strategies can be practiced.
