氢氧离子的浓度是监测水生生物状态或预测化学反应路径时必须测量的一个关键参数。本文介绍了一种用喷雾法制备单壁碳纳米管（SWCNTs）组成的简单快速响应pH传感器的方法。这种基于碳纳米管的传感器在不同羟基离子浓度的缓冲溶液中表现出安培响应。我们的研究结果表明，喷镀碳纳米管传感器可以作为化学传感器和生物传感器在未来的大通量设备。(c) 2006电化学学会。
The concentration of the hydroxyl ion is a critical parameter which must be measured for monitoring the condition of aqueous biological species or for predicting the path of chemical reactions. This paper describes a method for fabricating a simple and fast response pH sensor composed of single-wall carbon nanotubes (SWCNTs) using a spray. Such a CNT-based sensor shows amperometric response in buffer solution at different hydroxyl ion concentrations. Our results suggest that sprayed CNT sensors can be used as chemical sensors and biosensors in future large-scale throughput devices. (c) 2006 The Electrochemical Society.
