Abstract
Methods and devices for capturing and analyzing aerosolized particles in exhaled breath characteristic of a respiratory disease to enable rapid, low-cost point of care assays for several diseases including respiratory tract diseases such as COVID-19 are disclosed. The disclosed methods and systems selectively capture aerosolized particles using a packed bed column. The captured particles are then eluted using solvents and analyzed using analytical devices including MALDI-TOFMS.
