4D Electron Microscopy combines the spatial resolution of Electron Microscopes with the time resolution of modern laser systems, opening up exciting possibilities to study dynamics at the nanoscale. In the first part of the talk, I will present the development of a novel approach to study the material properties of biological nanostructures. By impulsively exciting a DNA structure and observing the resulting oscillations, it is possible to characterize its mechanical properties in much the same way mechanical engineers would study a macroscopic object. In the second part, I will describe experiments that for the first time allow one to precisely trigger and directly observe liquid flow in individual nanotubes. A wide range of nanoscale flow phenomena can be observed. In particular, it is possible to characterize viscous friction at the nanoscale to address fundamental questions in nanofluidics.
