Colorectal cancer (CRC) has been associated with changes in volatile metabolic profiles in
several human biological matrices. This enables its non-invasive detection, but the origin of …

Early-stage disease and cancer diagnosis are of particular importance for effective patient
identification as well as their treatment. Breath analysis is a promising method for this …

Background Effective screening for colorectal cancer can reduce mortality by early detection
of tumours and colonic polyps. An altered pattern of volatile organic compounds (VOCs) in …

For gas sensors, the ultrasensitive and highly selective detection of multiple components is
of great significance in a wide range of applications extending from environment to …

One in three cancer deaths worldwide are caused by gastric and colorectal cancer
malignancies. Although the incidence and fatality rates differ significantly from country to …

Electronic noses (e-nose) offer potential for the detection of cancer in its early stages. The
ability to analyse samples in real time, at a low cost, applying easy–to-use and portable …

The analysis of exhaled breath has attracted considerable interest for use in disease
