We report the development of a breath acetone analyzer using a sensor integrated with ZnO quantum dots (QDs) and a miniaturized gas chromatography (GC) column to separate acetone from human breath. The average size of the ZnO QDs, synthesized by a wet chemical method, is approximately 6 nm. The analyzer can detect acetone concentration as low as 0.1 ppm. The response of the ZnO QDs increases with increasing acetone gas concentration and is strongly correlated with the concentration (R2=0.9915). Additionally, the miniaturized GC column can effectively separate acetone gas from the breath. The acetone content in the breath of volunteers (who were on a ketogenic diet for 3 days and a normal diet) was monitored using the breath acetone analyzer.
