Detection of acetone in breath solution using nanocomposite CeO2-NiO-ZnO

Abstract

Acetone level of diabetic patients from their breath can be detected. The effect of CeO2 -NiO-ZnO nanocomposite was studied by adding different concentration of acetone. Structural (XRD, Raman) and morphological (SEM with EDAX) studied were done. The CV response of modified GCE with and without acetone was studied. It was observed that the current gets reduced in the presence of acetone. The sensor shows excellent sensitivity, selectivity and durability. The flexibility is an additional advantage of the sensor.
