微量全分析系统是现代分析科学的重要工具之一。在本文中，我们不仅提出了自供电的摩擦电微流控纳米传感器（TMN）与μ TAS集成的概念，而且还表明，开发的系统可以作为一种原位工具，以量化流动的液体微流控和溶液化学。当流体通过TMN时，TMN自动产生电输出，并且输出受到溶液温度、极性、离子浓度和流体流速的影响。自供电TMN可以检测水流速度、位置、反应温度、乙醇和盐浓度。我们还将TMN集成在一个mu TAS平台上，通过化学还原方法直接表征Au纳米颗粒的合成。
Micro total analysis system (mu TAS) is one of the important tools for modern analytical sciences. In this paper, we not only propose the concept of integrating the self-powered triboelectric microfluidic nanosensor (TMN) with mu TAS, but also demonstrate that the developed system can be used as an in situ tool to quantify the flowing liquid for microfluidics and solution chemistry. The TMN automatically generates electric outputs when the fluid passing through it and the outputs are affected by the solution temperature, polarity, ionic concentration, and fluid flow velocity. The self-powered TMN can detect the flowing water velocity, position, reaction temperature, ethanol, and salt concentrations. We also integrate the TMNs in a mu TAS platform to directly characterize the synthesis of Au nanoparticles by a chemical reduction method.
