Breath analysis

Definition

Breath analysis is a non-invasive method used to detect and quantify specific biomarkers in a person's breath, often employed for medical diagnostics and environmental monitoring. This technique leverages the presence of volatile organic compounds (VOCs) in exhaled air, which can indicate various physiological conditions or exposure to certain gases. The integration of advanced sensing technologies, such as quantum dots, enhances the sensitivity and accuracy of breath analysis, making it a promising tool for real-time health assessments and gas detection.

5 Must Know Facts For Your Next Test
