English abstract:
Two-photon processing enables free-form stereolithography with resolutions in the submicrometer range. Besides the generation of microscopic 3D-printed parts for optical and microelectronic applications, two-photon based techniques are especially attractive for creating tissue engineering constructs in the presence of living cells, as aqueous media and biological specimen are highly transparent at near-infrared wavelengths typically used. For biological application the versatility of two-photon processing is combined with functional materials to permit the tuning of mechanical properties and modification of biochemical triggers pertaining to the microenvironment of encapsulated cells, thus guiding their development. A range of materials exhibiting high biocompatibility are discussed in this contribution. Among them are highly efficient two-photon photoinitiators and hydrogel precursors based on gelatin and modified hyaluronic acid.
