摘要：
Microscopically structured colloidal crystals have been self-assembled using capillary forces onto chemically patterned surfaces. It is shown that the wetting meniscus on substrates patterned with hydrophobic and hydrophilic regions acts in this process as self-removing crystallization template (see Figure). By this method, closed-packed structures with a well-defined and intense bandgap in the visible range are obtained.
