在这项工作中，我们展示了一种新的表面增强拉曼散射（Sers）基板的灵感来自自然的蝴蝶翅膀鳞片纳米结构。通过简单、低成本的方法，我们合成了由二氧化锡（SnO 2）和银（Ag）纳米颗粒（NPs）组成的基底。显微照片和成分分析显示银-生物形态SnO 2的形貌继承了自然的三维（3D）周期性纳米结构，并表征了纳米复合材料的元素信息。以罗丹明6 G（R6 G）为分析分子，测量了Sers光谱。该基底具有良好的灵敏度（增强因子约为10（6））和重现性，表明了我们工作的有效性。预期该基底将是相关应用的潜在候选者。(C)2011爱思唯尔有限公司版权所有。
In this work, we demonstrated a novel surface-enhanced Raman scattering (SERS) substrate inspired by natural nanostructures of butterfly wing scales. By facile and low-cost procedures, we synthesized the substrate composed of tin dioxide (SnO2) and silver (Ag) nanoparticles (NPs). Micrographs and composition analyses exhibited the morphologies of Ag-Biomorphic SnO2 which inherited the natural three-dimension (3D) periodic nanostructures, and characterized the elemental information of the nanocomposites. SERS spectra were measured by using rhodamine 6G (R6G) as analyte molecules. The satisfying sensibility (with the enhancement factor about 10(6)) and good reproducibility of this SERS-active substrate revealed the effectiveness of our work. It is expected that this substrate would be a potential candidate for relative applications. (C) 2011 Elsevier B.V. All rights reserved.
