Abstract：
Miniaturized systems have attracted much attention with the recent advances in microfluidics and nanofluidics. From the capillary electrophoresis, the development of glass-based microfluidic and nanofluidic technologies has supported advances in microfluidics and nanofluidics. Most microfluidic systems, especially nanofluidic systems, are still simple, such as systems constructed with simple straight nanochannels and bulk-scale electrodes. One of the bottlenecks to the development of more complicated and sophisticated systems is to develop the locally integrated nano-electrodes. However, there are still issues with integrating nano-electrodes into nanofluidic devices because it is difficult to fit the nano-electrode size into a nanofluidic channel at the nanometer level. In this study, we propose a new method for the fabrication of local nano-electrodes in nanofluidic devices with nanofluidic and nano-electrochemistry-based experiments. An electroplating solution was introduced to a nanochannel with control of the flow and the electroplating reaction, by which nano-electrodes were successfully fabricated. In addition, a nanofluidic device was available for nanofluidic experiments with the application of 200 kPa. This method can be applied to any electroplating material such as gold and copper. The local nano-electrode will make a significant contribution to the development of more complicated and sophisticated nanofluidic electrophoresis systems and to local electric detection methods for various nanofluidic devices.
摘要：
随着微流体和纳米流体的最新进展，小型化系统吸引了很多关注。从毛细管电泳，基于玻璃的微流体和纳米流体技术的发展支持了微流体和纳米流体的进步。大多数微流体系统，特别是纳米流体系统，仍然很简单，例如用简单的直纳米通道和大尺度电极构建的系统。开发更复杂和复杂的系统的瓶颈之一是开发局部集成的纳米电极。然而,将纳米电极集成到纳米流体装置中仍然存在问题,因为难以在纳米水平将纳米电极尺寸适配到纳米流体通道中。在这项研究中,我们提出了一种基于纳米流体和纳米电化学的实验在纳米流体器件中制造局部纳米电极的新方法。在控制流量和电镀反应的情况下，将电镀溶液引入纳米通道。由此成功地制造了纳米电极。此外,纳米流体装置可用于应用200kPa的纳米流体实验。该方法可应用于任何电镀材料,例如金和铜。局部纳米电极将为开发更复杂和复杂的纳米流体电泳系统以及用于各种纳米流体设备的局部电检测方法做出重大贡献。
