(LEFT) Migration and alignment of rod-like microparticles on a curved interface formed around an elliptical micropost. The particles distort the interface to satisfy their wetting conditions. They align and migrate to minimize the interfacial surface area on the curved interface. (RIGHT) Schematic of a cross section of the interface, molded by pinning on the micropost.
