Early detection of biomarkers, substances that indicate an organism\u2019s disease or physiological state, could allow diagnosis and treatment before a condition becomes serious or irreversible. Recent studies have shown that your exhaled breath can contain molecules that may be biomarkers for recent exposure to environmental contaminants or for pathological conditions ranging from asthma to lung cancer. Scientists are working to develop biomarker \u201cfingerprints\u201d that could be used to diagnose a specific disease based on the amounts and identities of certain molecules in a patient\u2019s exhaled breath. An essential concept underlying this goal is that of a molecule\u2019s identity, which is determined by the numbers and types of atoms it contains, and how they are bonded together.
