Short summary
In this manuscript, we present a novel, first-principles method for the determination of surface tension of collected liquid aerosol particles. The method uses an atomic force microscope with a specially designed probe to directly measure the surface tension, a physical parameter required for Kohler theory. The measurements were verified using a standard, check-standard and then applied to a dry and humidified oxidized α-pinene aerosol system.
