Miniature Surface Enhanced Raman Scattering (SERS) sensors were fabricated by coating the carbon fiber microelectrodes with copper nanowires. The coating procedure, based on anodizing the copper wire in ultrapure water followed by cathodic deposition of the anode-derived material onto carbon fiber electrodes, provides a "clean" copper nanowire network. The developed miniature (10µm in diameter and 2mm in length) and nanoscopically rough SERS substrates are applicable in drug sensing, as shown by the detection and resolving of a range of seized designer drugs in trace amounts (microliter volumes of 10-10M solutions). The copper nanowire modified carbon microfiber substrates could also find further applications in biomedical and environmental sensing.
微型表面增强拉曼散射（SERS）传感器通过在碳纤维电极上涂覆铜纳米线来制备。该涂层工艺基于在超纯水中对铜丝进行阳极氧化，然后将阳极衍生材料通过阴极沉积到碳纤维电极上，从而提供了一个“清洁”的铜纳米线网络。所开发的微型（直径 10μm，长度 2mm）和纳米级粗糙的 SERS 衬底可用于药物检测，如通过检测和分辨痕量（微升体积为 10-10M 溶液）的一系列缉获的设计药物来证明。铜纳米线修饰的碳纤维微纤维衬底还可以在生物医学和环境传感领域得到进一步应用。
