Abstract

Zinc oxide is material compatible for biosensors, which has good properties such as low cost, high stability and wide band gap. Aim of this experiment is to study the effect of variations concentration of phosphate buffered saline solution on the performance of zinc oxide thin film as a glucose biosensor. A Zinc oxide thin film was fabricated by direct current (DC) sputtering coating method on the indium thin film glass substrate, with 20 Watt electric power and 2mTorr argon gas pressure. Characterization used XRD to determine the crystalline phase, The Zinc oxide thin film is characterized by a cyclic voltammetry (CV) with scan rate of 5mV / s and different concentration phosphate buffered saline solution. A wurtzite structure of Zinc oxide has been acquired the crystal size 233 run by using debye scherer equation (rietvield method) and optical band gap obtained 3.17 eV.
