A comparison of spectroscopic techniques for human breath analysis
The analysis of human breath has been driven to new heights and has great potential to impact our society in the area of medical science. Breath analysis is promising as non-invasive, simple and point-of-care clinical measurements to reduce the medical burden caused by invasive, time-consuming and expensive clinical devices. Spectroscopic techniques for breath analysis can offer information to ...
متن کاملBreath Analysis Using Laser Spectroscopic Techniques: Breath Biomarkers, Spectral Fingerprints, and Detection Limits
Breath analysis, a promising new field of medicine and medical instrumentation, potentially offers noninvasive, real-time, and point-of-care (POC) disease diagnostics and metabolic status monitoring. Numerous breath biomarkers have been detected and quantified so far by using the GC-MS technique. Recent advances in laser spectroscopic techniques and laser sources have driven breath analysis to ...
متن کاملInfluence of condensation temperature on selected exhaled breath parameters
BACKGROUND The effects of changes in cooling temperature on biomarker levels in exhaled breath condensate have been little investigated. The aim of the study was to test the effect of condensation temperature on the parameters of exhaled breath condensate and the levels of selected biomarkers. METHODS Exhaled breath condensate was collected from 24 healthy subjects at temperatures of -10, -5,...
متن کاملCondensation-induced jumping water drops.
Water droplets can jump during vapor condensation on solid benzene near its melting point. This phenomenon, which can be viewed as a kind of micro scale steam engine, is studied experimentally and numerically. The latent heat of condensation transferred at the drop three phase contact line melts the substrate during a time proportional to R (the drop radius). The wetting conditions change and a...
متن کاملSuper-sensitive seal whiskers feel fish breath.
Plunging through gentle swell in the northern oceans in search of food, harbour seals are guided by a cryptic superpower that few fish can evade. ‘Fish produce lots of water flow that remains in the water, even after the fish has gone’, says Wolf Hanke, from the University of Rostock, Germany, and it is these swirling wakes that betray the presence of fish dinners. A hungry seal can sense the t...
