AI Technical Summary
Current diagnostic methods for gastrointestinal, liver, and kidney diseases, as well as infections like H. pylori and cancer, are invasive, expensive, and lack affordable, portable, and user-friendly options, particularly for asymptomatic or subclinical conditions.
A universal electrochemical multianalyte breathalyzer device with sensors for ammonia and carbon dioxide detection, utilizing polyaniline and polypyrrole doped with specific dopants to measure breath gases, integrated with a processor and Bluetooth for data transfer, allowing self-administered point-of-care testing.
Provides accurate, non-invasive, and cost-effective detection of diseases by measuring breath gases, offering high sensitivity and specificity for conditions such as Celiac disease, H. pylori, and metabolic liver diseases, with potential for early intervention.
