3D printing biomaterials (with high resolution)

Combining adaptivity and stimuli-responsiveness with biocompatibility is crucial for the development of a new generation of materials with application in biomedicine. While the use of stimuli-responsive hydrogels is already well-established in the biomedical field, most of the applications are on the macroscale. Recently, there has been a growing interest in the use two-photon 3D laser printing for the fabrication 3D biomedical scaffolds with high precision at smaller scales. Hydrogels based on synthetic or natural polymers (e.g. proteins) are promising materials yet scarcely explored in the field of microprinting. Our aim is therefore to develop new printable biomaterials that enable new opportunities such as smart 3D/4D scaffolds for cells or in vivo 3D printing of microimplants in organisms.
