表面增强拉曼光谱（SERS）作为一种强大的分析工具得到了广泛的关注。尽管在设计SERS底物方面做出了许多努力，但创建能够检测不同目标分析物的通用底物仍然是一个巨大的挑战。在这里，我们报告了我们试图通过构建一种新型金属-氧化石墨烯纳米结构薄膜作为SERS衬底来解决这个问题。利用氧化石墨烯（GO）对芳香分子的高亲和力和纳米结构金属的SERS特性，该结构以带正电荷的结晶紫（CV）、带负电荷的苋菜红（苋菜红）和中性三苯基磷（PPh3）为模型分子，显示出对多种芳香分子传感的巨大潜力。
Surface-enhanced Raman spectroscopy (SERS) as a powerful analytical tool has gained extensive attention. Despite of many efforts in the design of SERS substrates, it remains a grand challenge for creating a general substrate that can detect diverse target analytes. Herein, we report our attempt to address this issue by constructing a novel metal-graphene oxide nanostructured film as SERS substrate. Taking advantages of the high affinity of graphene oxide (GO) toward aromatic molecules and the SERS property of nanostructured metal, this structure exhibits great potential for diverse aromatic molecules sensing, which is demonstrated by using crystal violet (CV) with positive charge, amaranth with negative charge, and neutral phosphorus triphenyl (PPh3) as model molecules.
