可控的双轴和单轴波纹（见图）是通过一个简单的两步方法制造的-金属沉积和随后的加热-基于形状记忆聚合物（预应力聚苯乙烯）片。皱纹的波长可以通过控制沉积金属的厚度来调节。的准备集成到微通道和它们的有效性，表面增强传感的？证明。
Controllable biaxial and uniaxial nanowrinkles (see figure) are fabricated by a simple two-step approach - metal deposition and subsequent heating - based on shape memory polymer (prestressed polystyrene) sheets. The wavelengths of the wrinkles can be tuned by controlling the thickness of deposited metal. The ready integration of the nanowrinkles into microchannels and their effectiveness in surface enhanced sensing is demonstrated.
