Paper Title:
Fabrication of Single Walled-Carbon Nanotubes Based pH Sensor Using Ultra-Precision Spray
  Abstract

The concentration of the hydroxyl radical is a critical parameter to be measured for monitoring the condition of aqueous biological species, or for predicting the path of chemical reactions. This paper describes a novel method for fabricating a very simple and fast response pH sensor compose of single walled-carbon nanotubes (SW-CNTs) using an ultra-precision spray. Such CNT-based sensor shows amperometric response in buffer solution at different hydroxyl radical concentrations and electrical conductance of SW-CNTs depends on the pH value. Our results suggest that sprayed CNT sensors are potential candidates as biosensors in future large-scale throughput devices.
