3D Printing: 3D-Printed Artificial Microfish (Adv. Mater. 30/2015).

J. Wang, S. Chen, and co-workers use a newly developed 3D printing technique on page 4411 to print freely swimming microfish with diverse designs.

3D-Printed Artificial Microfish.

Hydrogel microfish featuring biomimetic structures, locomotive capabilities, and functionalized nanoparticles are engineered using a rapid 3D printing platform: microscale continuous -optical printing (μCOP). The 3D-printed -microfish exhibit chemically powered and magnetically guided propulsion, as well as highly efficient detoxification capabilities that highlight the technical versatility of this platform for engineering advanced functional microswimmers for diverse biomedical applications.
