Diabetes mellitus, commonly known as diabetes, is a serious and chronic disease that affects around 400 million people worldwide, requiring critical, high-performance systems for non-invasive diagnosis and control. Over the last few decades, the emergence of electronic noses has demonstrated important progress in gas analysis technologies, because such electronic noses are low cost with high sensitivity and small dimensions, becoming promising main candidates for the diagnosis of diseases through the analysis of exhaled breath. SAW sensors based on ZIF nanocrystals as sensitive layers are proposed in this work to detect breath markers related to diabetes and other associated health disorders. The results exhibit excellent performance of the SAW/ZIF electronic nose, indicating its potential as a non-invasive system that can contribute to the diagnosis and control of diabetes in real cases.
