In recent decades, biomarker gas detection has become crucial for early disease diagnosis and environmental monitoring. Various VOCs, such as acetone for diabetes, are key indicators of physiological and pathological states, necessitating reliable detection methods. Among these, p-cresol is a significant biomarker for chronic kidney disease (CKD) [1]. Monitoring these biomarkers in exhaled breath or skin gas is vital for early detection and management. Skin gas sensors, in particular, offer non-invasive, continuous monitoring, providing real-time data without the discomfort of blood tests. Traditional metal oxide semiconductor (MOS) gas sensors are valued for their high sensitivity, compact size, and affordability [2], but they suffer from poor selectivity and characteristic drift. Our study addresses these issues by introducing a highly sensitive WO₃ nanowire based sensor, developed through PLD and lithography processes, optimized for detecting p-cresol, thus enhancing accurate health monitoring.
