A team of researchers, including Cluster Doctoral Researchers Clara Vazquez-Martel, and Elisa Genthner and PIs Martin Bastmeyer and Eva Blasco, extracted and functionalized microalgae lipids for use as inks in two-photon 3D laser printing. Microalgae offer significant advantages as 3D printing materials due to their reduced carbon footprint and superior bio- and cytocompatibility. Their CO2 fixation during cultivation and rapid growth make them ideal for creating sustainable, eco-friendly materials with promising applications in biocompatible implants and non-toxic 3D cell scaffolds.
