Exhaled breath analysis has emerged as a promising, non-invasive diagnostic tool for the early detection of metabolic disorders and respiratory diseases. Volatile organic compounds (VOCs) serve as critical biomarkers for conditions like diabetes and lung cancer. However, designing sensor materials with high sensitivity and absolute selectivity remains a significant hurdle due to the complex environment of human breath. This work establishes a fundamental theoretical framework to evaluate and predict the VOC-sensing performance of semiconductor materials. Acknowledgement.
