A new cluster publication with first author Niklas Schwegler has been published in Small. Postdoctoral Researchers Maria Villiou, Federico Colombo, Barbara Schamberger and Principal Investigators Christine Selhuber-Unkel, Franziska Thomas and Eva Blasco are also involved. The scientists developed a direct method to fabricate 3D microstructured cell-adhesive and cell-repellent multimaterials using two-photon laser printing. This method offers better molecular control, high customizability, and fast and precise 3D fabrication, suitable for a variety of applications, such as cellular studies in complex environments.
