Abstract: Systems and methods to provide rapid and autonomous detection of biological and chemical analyte particles in gas and liquid samples. Systems and methods for capturing and identifying biological and chemical aerosol analyte particles using matrix assisted laser desorption mass spectrometry (MALDI-MS) and using time-of-flight mass spectrometry (TOFMS) are disclosed. High specificity for capture and detection of aerosolized fentanyl was demonstrated using a portable sample capture and analysis system.

Abstract: Systems are methods for identifying the composition of non-biological aerosol particles or biological aerosol particles including water bound to the surface of the particles, without pre-treatment using complex organic MALDI matrices. A continuous timing laser may be used to index the aerosol particles, determine optical particle properties, and trigger an IR pulse ionization laser. Ionized fragments, and optionally photons, associated with each particle produced by ionization of the particles the IR ionization laser is analyzed using one or more detectors including a TOFMS detector and an optical detector. Unique mass spectral data and optical data associated with each indexed particle is compiled using data fusion to generate a compiled data set. The compiled optical data is compared with a training data set comprising a knowledge base of known aerosol particles to predict aerosol particle composition.

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.
