Point-of-care testing (POCT) for H. pylori is crucial for immediate diagnosis and treatment, especially in resource-limited settings. Catalytic materials can be integrated into portable diagnostic devices to enable rapid and accurate detection. These devices often employ catalytic reactions to amplify the detection signal, making it possible to identify low levels of H. pylori in samples such as breath, blood, or stool. The use of enzymatic catalysts and synthetic chemical catalysts in POCT devices has shown great promise in reducing the time and cost associated with traditional diagnostic methods.
