Bi-metallic patterns with array of Pt discs decorated by Au rings were fabricated onto the substrate by a templated-self-assembly procedure in which multi-step self-assembly processes were involved. The original pattern was established by using the breath figure method. The bi-metallic sample with Au rings exhibited rather high sensitivity as well as great reproducibility within the array in surface-enhanced Raman scattering test.

通过模板自组装程序制备具有金微环上层结构的有序双金属阵列及其SERS应用。

通过模板化的自组装程序将涉及多个步骤的自组装过程，将具有由Au环装饰的Pt圆盘阵列的双金属图案制作到基板上。通过使用呼吸图方法建立了原始模式。在表面增强的拉曼散射测试中，具有Au环的双金属样品在阵列中显示出相当高的灵敏度以及重现性。
