I will present theory and molecular modelling of the charged-induced instabilities of charged droplets with linear dimensions in the nanometer range. Differently from experimental and numerical studies of macroscopic drops, in the systems that I investigate the electric field is caused by a highly charged macroion found in the interior of the droplet. The geometry of the macroion (spherical, finite length rod) determines the electric field and opens up the possibility for different droplet morphologies that have not been studied so far (Fig. 1).
