A microfocus / electrodynamic levitation study of a model system for respiratory aerosol droplets: effect of lung surfactant DPPC on salt b

We will study electrodynamically levitated droplets of a model respiratory aerosol containing the lung surfactant DPPC and salts, using microfocus SAXS/WAXS in a controlled humidity cell. We will explore the impact of the surfactant self-assembly on salt crystallisation as the droplets lose water and equilibrate with their environment. Our findings will help understand the effect of aerosol microenvironment on virus stability in exhaled droplets, which impacts on transmission of airborne diseases.
