Patterning microsphere surfaces by templating colloidal crystals.
By using the upper single or double layers in colloidal crystals as masks during Au vapor deposition, various Au patterns have been successfully constructed on the surfaces of the lower spheres. The dimension and geometry of the Au patterns obtained are dependent on the orientation of the colloidal crystal templates. Our patterning procedure is independent of the curvature and chemical composition of the surfaces, which definitely pave a promising way to pattern highly curved surfaces.
