'A SENSOR COMPOSITION FOR ACETONE DETECTION IN BREATH'

摘要

The present invention provides an improved sensor composition for acetone detection in breath for diabetic diagnostics and the process of preparation thereof. The sensor composition is based on semiconducting nanostructured γ-Fe2O3. The sensor is selective to low concentration of acetone, the breath biomarker of diabetes, in presence of a high amount of moisture normally present in breath. Such semiconductor sensors for diabetes monitoring are inexpensive, rugged, patient-friendly and on the top, non-invasive.
