Our group has been operating since 1997 in the field of fabrication and characterization of new materials for photonics, optical sensing and tissue engineering. NeMO group description (ITALIAN)
3D printing is the breaking technology in tissue engineering. The ability to simulate in vitro the natural environment for a cell culture can lead to faster developing of biological tissues and organoids for implants and to a drastical reduction of the costs for drug testing. Another important aspect in this work is to provide a model to study how shape and mechanical properties of the scaffold influence the differentiation of stem cells. The biocompatible material used in this project is the hydrogel, chosen for its ability to absorb large amount of water up to 1000 time its own mass. We realized scaffold based on high MW-PEGda (PoliEtilenGlicol diacrilate) via one- and two-photon polymerization using a femtosecond pulsed laser. Alternatively, a microstereolithographic approach uses a liquid filter as a mean for depth control in the photopolymerization process.
