In article number 1602769, H. Yu, L. Liu, and co-workers demonstrate a Tetris-inspired approach to fabricate 3D heterogeneous microscale tissue from hydrogel building blocks. The investigated system combines optofluidic maskless lithography and optically induced dielectrophoresis (ODEP). The customized bio-microstructures in Tetris shapes are dynamically synthesized using an optofluidic maskless lithography system and then transferred to an optically induced electrokinetics (OEK) chip for manipulation and assembly.
