Resolving the tension: Complex particles with various shapes such as bullets, cylinders, discs, hearts, hexagons, and Janus particles can be synthesized by two different surface-tension-induced flow sequences (A and B; see picture, scale bars=100 μm). The particles produced by using this approach can be exploited as anisotropic building blocks for the fabrication of complex systems by combination of the two sequences.
