The diffusion of charged nanoparticles at the air/water interface — •Tobias Gehring and Thomas Fischer — The University of Bayreuth

We measure the electrostatic effects on the diffusion of nanoparticles at the air/water interface. Using particle tracking of fluorescent nanoparticles on air/water interfaces of different ionic strength we are able to determine the change of diffusion of the particles and hence their immersion into the interface with the salt content. First measurements of those electrostatic effects will be presented.
