摘要：
We have shown a self-assembly of colloidal particles in a two-dimensional structure on a patterned surface with wettability. The assembling process relies on the wettability change of a liquid crystal (LC), used as a colloidal suspending medium, on an alignment surface with varying the ultraviolet exposure. A close-packed structure of the colloidal particles was obtained by adjusting the diameter of the wetting area relative to the particle size and the strength of the wettability. The self-assembling technique would be applicable in various fields of microphotonics and health sciences.
