Properties of aerosol used in the delivery of drugs to the lungs

We are exploring in this project the coupling of mass and heat transfer that occurs during the rapid evaporation or growth of aerosol. Measurements are providing direct in situ information on the evolving size and composition of particles with high time resolution. New work is examining the hygroscopic behaviour of typical drug excipients and surfactants used in pulmonary aerosol delivery and the kinetics of their size response.
