This paper proposes a self-deformable structure consisting of tethered multiple micromotors. Pt/Au segmented microrods formed by electrodeposition were used as the micromotors. To fabricate flexible tethers, several approaches were tried including metal backbones, metallized DNA strands, and polymers stacked by layer-by-layer (LbL) self-assembly. For the metal backbones, shadowing effect of sputtering...
A major challenge in tissue engineering is the fabrication of vascular networks capable of delivering oxygen and nutrients throughout tissue constructs. Because cells located more than a few hundred micrometers away from the nearest capillaries are susceptible to oxygen shortages, it is crucial to develop microscale technologies for engineering a vascular structure in three-dimensionally thick tissues...
