On Non-Invasive Measurements of Exhaled Aceton Using Metal Oxide Nanosensors

Aroutiounian VM*

The paper presents and discusses works carried out both at Yerevan State University and abroad on non-invasive metal oxide sensors (chemiresistors) for acetone exhaled by a diabetic. The technologies and parameters of chemiresistors based on tin dioxide, tungsten trioxide, zinc oxide, Fe₂O₃, In₂O₃ and TiO₂ developed at YSU and in the world are presented. Most likely, it makes sense to start investigations start with concentration 1 ppm acetone. The response of the MWCNT-doped SnO₂ chemiresistors was measured at a concentration of acetone from 1 to 12 ppm, characteristic of diabetics at a relatively early stage of the disease.
