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 -- and improve patients' prospects.
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 -- and improve patients' prospects. Researchers report developing ultrasensitive, nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath of people with lung cancer .
People breathe out many gases, such as water vapor and carbon dioxide, as well as other airborne compounds. Researchers have determined that declines in one exhaled chemical -- isoprene -- can indicate the presence of lung cancer. However, to detect such small shifts, a sensor would need to be highly sensitive, capable of detecting isoprene levels in the parts-per-billion range.
COVID-19 can spread from asymptomatic but infected people through small aerosol droplets in their exhaled breath. Most studies of the flow of exhaled air have focused on coughing or sneezing; ...
