Abstract

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.
