초록
Exhaled breath analysis has emerged as a non-invasive and cost-effective approach in medical diagnostics, particularly for detectingbiomarkers such as acetone. This study presents the synthesis and characterization of Cr-doped ε-WO3spheres designed to improve gassensing performance. These spheres were synthesized via ultrasonic spray pyrolysis, resulting in a material with a complex compositionexhibiting high sensitivity and selectivity towards acetone over ethanol (response ratio = 13.2 at 325oC). The enhanced acetone sensitivity of the Cr-doped WO3sensor is attributed to the strong interaction between the spontaneous electric dipole moment of ε-WO3and the significant dipole moment of acetone. This sensor can detect exhaled acetone, facilitating effective monitoring of a ketogenicdiet.
