Exhaled breath is the best-suited biofluid for direct access to physiological changes in lung function and the “exposure to effect” pathway of the toxicity of exogenous gas-phase chemicals. This is particularly true for any analytical schemes that require rapid response; unlike blood and urine sa...
In addition to breast cancer, formaldehyde has been proposed as a possible biomarker for prostate and bladder cancers [197]. Using a specially designed array of cross-reactive nanosensors based on organically functionalized Au nanoparticles, Peng et al. investigated the exhaled alveolar breath of 177 ...

It should be noted that breath samples are considered rather stable; short-term storage of 1 month did not affect sample stability, as demonstrated in a urea breath best samples for the diagnosis of Helicobacter pylori [56]. Furthermore, Kang and Thomas [57] demonstrated the storage of VOCs ...
