Abstract (englisch):

The transition from traditional 2D cell culture models to physiologically relevant 3D models has revolutionized biomedical research. Hydrogels are frequently used to produce realistic 3D models with applications in tissue engineering, disease modeling and high-throughput screenings. However, integrating 3D cultures into high-throughput screening workflows presents challenges, including automation compatibility and cost constraints. Addressing these challenges requires innovative approaches that enable miniaturization, automation, and cost reduction while maintaining experimental fidelity. The Droplet Microarray (DMA) platform, based on hydrophilic-superhydrophobic surface patterning, facilitates the formation of homogeneous nanoliter-hydrogel arrays containing cells or spheroids. This method allows rapid dispensing of hundreds of nanoliter-hydrogel droplets with precise control over volume and cell density, reducing reagent consumption and offering high-throughput applications. The stable nanoliter-hydrogel array on a chip allows for experimental procedures like washing and medium immersion. We demonstrated that spheroid-containing droplets can be gelled at any point of the experiment, enabling the fixation of cell structures on the surface. ... mehr
