Electrostatic deposition of nanoparticles into live cell culture using an electrospray differential mobility analyzer (ES-DMA)

► Electrostatic deposition of aerosolized nanoparticle to live cells. ► Cellular viability is achievable by preserving a thin liquid layer covering the cells. ► Higher humidity environment increases the time of particle exposure. ► Localization of particles in cell cytoplasm is observed with confocal microscopy. ► Diffusion is the dominant particle transport mechanism.
