Die additive Fertigung (3D-Druck) wurde in den frühen 1980er Jahren entwickelt und gewann seitdem durch stetige Verbesserungen an Bedeutung. Gebiete wie die Biotechnologie, die Pharma- und die Chemieindustrie, wo besonders ...

Hydrogels consist in a water-swollen and self-supporting polymeric network. They can undergo extremely large deformations, their mechanical properties can be tuned finely, and they permit the diffusion and release of ...

Hydrogel waveguides have found increased use for variety of applications where biocompatibility and flexibility are important. In this work, we demonstrate the use of polyethylene glycol diacrylate (PEGDA) waveguides to ...

Gelatin-methacryloyl (GelMA) is a semi-synthetic hydrogel which consists of gelatin derivatized with methacrylamide and methacrylate groups. These hydrogels provide cells with an optimal biological environment (e.g., RGD ...

Advances in photomedicine and optogenetics have defined the problem of efficient light delivery in vivo. Recently, hydrogels have been proposed as alternatives to glass or polymer fibers. These materials provide remarkable ...

The spatially-targeted fabrication of bimetallic microstructures coexisting in the supporting hydrogel is demonstrated by multi-photon photoreduction. Microstructures composed of gold and silver were fabricated along a ...
