Advances in Liquid Phase Electron Microscopy: Imaging Strategies for Soft Materials and Controlled Motion of Nanoparticles 

In-situ cells developed for the transmission electron microscope (TEM) allow performing experiments on nanoscale materials in liquids and gases, even while heating or under application of electric fields, while imaging them at near-atomic resolution. Of these two, in particular liquid cell TEM (LC-TEM) imaging is particularly sensitive to e-beam effects [1]. In this seminar I will discuss recent progress made at Utrecht University in the imaging of induced transitions. The first model system is p-NIPAM, a thermoresponsive biocompatible polymer that reversibly compresses when heated from room temperature to a temperature of 40 °C and vice versa. When immersed in water and thus swollen, the density of p-NIPAM is almost the same as that of water, while it is extremely sensitive to e-beam irradiation. Eventually a suitable approach was found and the thermoresponsive response was successfully imaged [2]. The second model system is a ‘rattle particle’ consisting of a mobile core particle inside a larger silica shell where the porous shells are filled with liquid. Depending on the salt concentration in the liquid, the potentials between the core and shell could be adapted to confine the core particle at the center of the shell, or be adapted in such a way that the core particle could explore nearly the entire volume of the spherical cavity [3]. Finally, preliminary results on the application of an AC electric field on the rattles show that the direction of the motion of the cores, either parallel or orthogonal to the field, could be controlled depending on the frequency of the applied field.
