Recently developed super resolution microscopy techniques can provide nanoscopic optical resolution. We demonstrate their validity by imaging single microgels at different stages of the volume phase transition. Next, we map out the different contributions of deformation, interpenetration and compression from the marginally jammed state to deeply into the overpacking regime. We find that initially interpenetration and shape deformation are dominant until, in the highly overpacked state, only compression remains as a means for further densification of the suspension.
