A research team led by Prof. Geun Hyung KIM of the Department of Bio-Mechatronic Engineering proposed the world’s first hybrid cell-printing technique that combines a conventional extrusion-based cell-printing process with an electrohydrodynamic jet. The electric field stabilized the extruded struts of cell-embedding-hydrogel and reduced the damage to dispensed cells caused by the high wall shear stress in the dispensing nozzle. The new cell-printing process was optimized in terms of various processing parameters, applied electric field strength, nozzle movement speed, and distance between the nozzle tip and working stage. Because of these unique features, scholars in the field and cell-printing companies show their interest to learn more about this technique.
To overcome shortcomings of 3D cell-printing process such as unstable flow and potential loss of cell viability, the research team suggested an innovative cell-printing process that combines a conventional extrusion-based cellprinting process with an electric field. The electric field in the cell-printing process stabilized the extruded struts of bioink and dramatically reduced the damage to dispensed cells caused by the high wall shear stress in the dispensing nozzle.
