将一种新型的双层二元胶体晶体与脉冲激光沉积技术相结合，提出了一种独特的方法来制造具有微、亚微和纳米结构的复杂分层周期阵列。该方法具有通用性，可以在复杂的层次周期阵列中轻松制备不同材料的纳米结构。与传统的光刻技术相比，这种方法具有低成本的优势。这些制备的独特结构不能通过常规光刻直接制造。这些特殊的分层结构阵列具有良好的结构增强性能，包括不受紫外线照射的超亲水性和表面增强拉曼散射（SERS），这对于设计微/纳米器件，如生物传感器或微流体器件具有很高的价值。
A unique approach for fabricating complex hierarchical periodic arrays with trinary stepwise architectures of micro- and submicro- as well as nanosized structures by combining a novel double-layered binary colloidal crystal with pulsed laser deposition techniques is developed. The present strategy is universal and nanostructures with different materials can be easily prepared in the complex hierarchical periodic arrays. This approach offers the advantage of low costs compared to conventional lithographic techniques. These as-prepared unique structures cannot be directly fabricated by conventional lithography. These special hierarchically structured arrays demonstrate fine structure-enhanced performances, including superhydrophilicity without UV irradiation and surface enhanced Raman scattering (SERS), which is highly valuable for designing micro/nanodevices, such as biosensors or microfluidic devices.
