Abstract
Inspired by the nipple arrays covering mosquitoes' eyes and the heterogeneous textured bumps on beetles' backs, we have developed a new kind of Janus particle with multiplexed features, such as different boss arrays and wettability compartmentalized on the same surface, and an anisotropic color and magnetic properties. The prepared Janus particles can be anchored at the air-water interface and act as a highly flexible barrier for preventing coalescence of water droplets. The incorporation of magnetic nanoparticles can give the Janus particles magnetic responsiveness for controlled transportation and coalescence of liquid marbles, while the structural colors in the Janus particles can be employed for barcoding of the encapsulated liquid marbles. We believe that these small Janus particles have great potential as components for constructing intelligent interfacial objects. © 2012 American Chemical Society.
