ZnO Nanostructured thin film of thickness 200nm was deposited on quartz by spray pyrolysis technique; further interdigitated ITO electrodes were fabricated by lithography. Compositional, surface morphology and electrical characterization of ZnO nanostructure thin film was done using X-ray photo electron spectroscopy (XPS), Secondary electron microscopy (SEM), and current-voltage (I-V) measurement...
An electrochemical amperometric sensor measures the electric current on the surface of the working electrodes and estimates the concentration of chemical or biological species. Electrochemical sensor is fast and selective but electrochemical sensing is a complex phenomenon involving both physical and chemical processes. With a view to understand the basic operation of electrochemical sensor, present...
