Zinc oxide nanonail based chemical sensor for hydrazine detection

Using ZnO nanonails, a hydrazine electrochemical sensor has been fabricated, for the first time, which showed a high and reproducible sensitivity of 8.56 mu A cm(-2) mu M-1 with a response time less than 5 s, a linear range from 0.1 to 1.2 mu M and a correlation coefficient of R = 0.999. The limit of detection (LOD), based on the S/Nratio, was estimated to be 0.2 mu M.
