In this study, a recently developed approach that combines two different technologies was developed in order accurately understand the dynamics of airborne diseases transmission.

After a dissemination event, the evaporation and rehydration processes occurring during a droplet’s lifetime produce rapid changes in the particles’ sizes that will affect most of the physicochemical properties of the biological aerosol (i.e. solute concentration, density, viscosity, etc.). These dynamics could also impact the viability of the microbes contained within the bio-aerosol droplets and will influence the length of time these microorganisms survive while suspended in the aerosol phase.
