Ultrasensitive Detection of Dimethylamine Gas for Early Diagnosis of Parkinson’s Disease Using CeO2-Coated Ti3C2Tx MXene/Carbon Nanofibers

Parkinson's disease is a prevalent neurological disorder, with dimethylamine (DMA) recognized as a crucial breath biomarker, particularly at the parts per billion (ppb) level. Detecting DMA gas at this level, especially at room temperature and high humidity, remains a formidable challenge. This study presents an ultrasensitive chemiresistor DMA gas sensor, leveraging the CeO
