在此，我们报告了几种磁性碳结构的合成，从球体（CS）到更细长的结构，通过定制化学气相沉积参数得到管和纤维。这些CSs为基础的产品，从纳米到微米尺寸，进行了研究，从形态的角度来看，使用扫描电子显微镜，能量色散X-射线光谱，和拉曼光谱。这些碳结构与丝网印刷电极相结合，突出了它们对检测几种物质的电化学有效性，即铁氰化物、抗坏血酸、多巴胺、半胱氨酸、血清素和NADH。除了改善印刷电极处的电化学性能之外，碳晶格内铁核的存在可能赋予这些基于CS的结构在修复/传感领域中的未来应用。本文提供了一些初步应用，表明这些材料可以容易地用于收集物种，并连续地与印刷电化学传感器耦合。(C)2018爱思唯尔有限公司版权所有
Herein, we report the synthesis of several magnetic carbon structures starting from spheres (CSs) to more elongated structures to get tubes and fibers by customizing chemical vapour deposition parameters. These CSs-based products, ranging from nano-to micro-size, were investigated by morphological point of view using scanning electron microscopy, energy dispersive x-ray spectroscopy, and Raman spectroscopy. These carbon structures were combined with screen-printed electrodes highlighting their electrochemical effectiveness towards the detection of several species, i.e. ferricyanide, ascorbic acid, dopamine, cysteine, serotonin, and NADH. The presence of iron nuclei within the carbonaceous lattices, besides having improved the electrochemical performances at the printed electrodes, might confer these CSs-based structures a future application in the field of remediation/sensing. Herein, some preliminary applications were provided showing that these materials can be easily employed to collect species and, successively, coupled with printed electrochemical sensors.
