Light-Induced 3D Bioprinting Technologies

Daniel Nieto, Head of "Advanced engineering solutions for biofabrication Lab", MASSTRICHT UNIVERSITY

Light-based biofabrication methods, including Digital Light Projection, volumetric bioprtinting and a light-based biopen, have been developed and used to generate biological scaffolds complex tissue structures and drugs. Some theoretical mechanisms, which condition cell response during bioprinting using light based technologies are sumarized. Also a brief look at the light–biomaterial interaction for a better understanding of how linear effects (refraction, reflection, absorption, emission, and scattering) and nonlinear effects (two-photon absorption) influence the biofabricated tissue structures and identify the different parameters essential for maintaining cell viability during and after bioprinting.
