As people sit and talk inside a conference room or huff and puff as they work out in a gym, their exhaled breath accumulates in the air. Unless that space is well ventilated, all that exhaled breath ...

Exhaled breath contains chemical clues to what's going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses -- ...

The measurement of exhaled nitric oxide and carbon monoxide concentrations is an emerging method of monitoring airway inflammation longitudinally in community-based studies. Inhaled concentrations of ...

In a recent study posted to Preprints with The Lancet*, researchers found evidence that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) particles are released directly into the air ...

Researchers have shown that exhaled human breath contains a characteristic molecular "fingerprint". Stable, specific 'breathprints' unique to an individual exist and may have applications as ...

MIT engineers have designed nanoparticle sensors that can diagnose lung diseases. If a disease-associated protein is present in the lungs, the protein cleaves a gaseous molecule from the nanoparticle, ...

A few exhaled volatile organic compounds — specifically decane and nonadecane — showed potential to identify allergic patients among those with chronic rhinitis, with 76.5% sensitivity and 69.2% ...

A recent study measured exhaled breath condensate (EBC) content that contained ultrafine particles (UFP) as a reflection of inflammation and oxidative stress in patients with chronic obstructive ...

Sept. 29 (UPI) --Researchers have developed a new nasal cleansing spray, featuring calcium-rich salts, that can kill sub-micron aerosolized particles, according to a study published Tuesday in the ...
