Solution AFM Studies of Molecule Crystals: Exploiting Photon Pressure — •Sven Kraft, Heinrich Behle, Kai Wardelmann, Mohammadreza Bahrami, Björn Vogler, Mirjam Samelin, Semjon Köhnke, Boris Hage, Ingo Barke, and Sylvia Speller — University of Rostock, Institute of Physics, 18059 Rostock, Germany

Atomic Force Microscopy in liquids is an important tool for imaging processes in molecular layers and films. Dynamic AFM usually suffers from distorted resonance curves of the cantilever oscillation in the medium. Driving the cantilever via photon pressure is an option to improve the cantilever oscillation and acquire topographies in solutions in dynamic mode. We aim to test this approach with the aggregation and dissolution of molecule crystals in a number of solvents, in order to gain insight into the internal structure of such crystals.
