显微结构的胶体晶体已经使用毛细力自组装到化学图案化的表面上。结果表明，在此过程中，具有疏水和亲水区域图案的基底上的润湿弯月面充当自移除结晶模板（见图）。通过这种方法，获得了在可见光范围内具有良好定义和强烈的带隙的紧密堆积结构。
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.
