Mechanics of DNA Structures and Liquid Flow in Nanotubes: Observing Nanoscale Dynamics by 4D Electron Microscopy

Date Do, 12.03.2015 - Do, 12.03.2015
Time 16.30
Speaker Dr. Ulrich Lorenz, CALTECH, USA
Location EPFL, ISIC, CH G1 495
Program ISIC Physical Chemistry Seminar by Dr Ulrich Lorenz

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.
