Abstract
The investigation of novel ternary metal oxide based breath acetone chemiresistors has garnered interest in a facile diagnosis of diabetes via breath analysis. In this work, a sodium dodecyl sulfate (SDS) surfactant has been employed to tune the morphology of olivine type Cd2GeO4 from nanoparticles (CGO-NPs) to hexagonal plates (CGO-HPs), resulting in a significant enhancement in response to acetone. The CGO-HPs based acetone chemiresistor shows a high response (7.87) to 10 ppm acetone at 275 °C, with fast response (12 s) and recovery (35 s) times, as well as commendable reproducibility. Moreover, the CGO-HPs chemiresistor could accurately and promptly identify the real diabetic patients via breath acetone analysis, demonstrating the potential of ternary oxide based acetone chemiresistors in non-invasive diabetic diagnosis.
