Exhaled breath testing – A tool for the clinician and researcher
Paediatric Respiratory Reviews, 2019Exhaled breath is a robust matrix of biomarkers divided between three fractions - gaseous breath, volatile breath, and breath condensate. Breath is collected non-invasively through bags (for gaseous breath), cold condensation chambers (breath condensate),

Lung cancer biomarkers in exhaled breath
Expert Review of Molecular Diagnostics, 2011Lung cancer is the leading cause of cancer-related mortality worldwide. Methods for early detection of lung cancer, such as computerized tomography scanning technology, often discover a large number of small lung nodules, posing a new problem to radiologists and chest physicians. The vast majority of these nodules will be benign, but there is currently
