Linking the chemistry between microscopic and nanoscopic-sized droplets

Multi-scale modeling of electrospray ionization mechanism supports that solvated proteins are ejected from Rayleigh jets emanating from a droplet's surface. These progeny droplets take "star", "pearl-necklace", and "gradually unraveled yarn ball" shapes. The charging mechanism of the proteins has a reciprocal relation with the droplet shape.
