Direct observation of structural heterogeneity and tautomerization of single hypericin molecules
Quan Liu, Frank Wackenhut, Liangxuan Wang +6
Tautomerization is a fast chemical reaction where structures of the reactants differ only in the position of a proton and a double bond. Tautomerization often occurs in natural sub…

Direct phase mapping of the light scattered by single plasmonic nanoparticles
Otto Hauler, Frank Wackenhut, Lukas A. Jakob +5
In this work, we present a novel technique to directly measure the phase shift of the optical signal scattered by single plasmonic nanoparticles in a diffraction-limited laser focu…
