Investigation of Different Materials as Acetone Sensors for Application in Type-1 Diabetes Diagnosis

Abstract

ARTICLE INFO abstract Diabetes, one of the most rapidly-growing chronic diseases in the world, is overall relative expensive on both diagnosis and monitoring. Breath acetone has proven to be a biomarker of diabetes which is a metabolite with a strong correlation with blood glucose. Measuring the concentration of acetone in exhaled breath can provide a non-invasive, low risk of infection, low cost, and convenient way to screen diabetics at the early stage and daily monitor the health condition of diabetics. Several materials have been investigated for their ability to detect of breath acetone. The preliminary results show that nano-structured K 2 W 7 O 22 (KWO), a new functional semiconducting material, synthesized by hydrothermal method, can effectively detect breath acetone at room temperature. This paper emphasizes that the sensing performance of KWO on breath acetone. In addition, a comparison between KWO with other materials for application in sensing acetone is discussed.
