DESCRIPTION:Anisotropic Janus colloids are emerging building blocks for pr
 ogrammable self-assembly of materials. So far\, experimental studies on th
 e self-assembly of Janus particles have focused on the behavior of small c
 lusters formed in dilute suspensions\, mainly due to the scarcity of the a
 vailable colloids. Here\, we demonstrate a simple\, yet versatile method y
 ielding monodisperse colloids that possess anisotropy in both shape and ch
 emistry. We observe that these particles exhibit hierarchical self-assembl
 y: they first form inverse cylindrical "micelles"\, which subsequently sta
 ck into highly ordered lanes and ultimately form macroscopic structures. C
 omputer simulations shine further light on the observed structures.
