A team of scientists including Cluster Doctoral Researchers Philipp Mainik and Magdalena Fladung, Cluster Scientists Camilo Aponte-Santamaría and Irene Wacker, and Principal Investigators Martin Bastmeyer, Rasmus R. Schröder, Frauke Gräter and Eva Blasco, has developed a collagen type I methacrylamide (ColMA) ink that enables precise 3D printing of microstructures using two-photon laser printers. The ink, storable at room temperature, enables structures that reversibly fold and unfold with temperature changes, mimicking natural extracellular matrix behavior. This breakthrough opens new possibilities for dynamic biomaterials, advanced tissue scaffolds, and 4D printing.
