Implication
Experimental study reveals selective acetone detection using room-temperature ferroelectric ε-WO3 nanoparticles, suggesting potential for noninvasive breath-based diabetes diagnosis.
Key Points
- Synthesize and stabilize ferroelectric ε-WO3 nanoparticles above room temperature to evaluate their potential for selective acetone sensing in breath-based diabetes diagnosis.
- Synthesized ferroelectric ε-phase tungsten trioxide (ε-WO3) nanoparticles.
- Stabilized the ferroelectric phase above room temperature and fabricated a gas sensor to test acetone response.
- Achieved room-temperature stabilization of ferroelectric ε-WO3 nanoparticles for the first time.
- Demonstrated high sensor sensitivity and selectivity toward acetone gas, indicating viability for noninvasive diabetes screening.
