Welcome to the Wöll Research Lab

AK Wöll at the RWTH Aachen University (since June 2014)

AG Wöll at the University of Konstanz (end of 2013)



Our research focuses on single molecule fluorescence spectroscopy and microscopy in soft matter.


Research topics:

  • Diffusional changes and evolving heterogeneities in single molecule mobility during polymerization and their influence on polymerization kinetics
  • Single molecule dynamics in thin polymer films in vicinity of the glass transition temperature
  • Photocleavable energy transfer dyads for single molecule microscopy with improved resolution
  • Fluorescence labeling and diffusional studies of anisotropic nanoparticles

Techniques:

  • Single molecule fluorescence microscopy at room and elevated temperatures
  • Fluorescence correlation spectroscopy
  • Fluorescence anisotropy spectroscopy
  • Raman spectroscopy and microscopy

Observations:

  • Translational and rotational motion of single molecules
  • Changes in fluorescence and Raman spectra
  • (Single molecule) FRET efficiencies


Are you a highly motivated student interested in one or a combination of the following topics?

  1. (Single molecule) fluorescence spectroscopy techniques, modifying setups, optics and measurement procedures
  2. Polymer synthesis, characterization and dynamics
  3. Theory of diffusion in polymer solutions and polymers
  4. (Organic) Synthesis and derivatization of dyes

Very nice, then I am waiting for YOU! Just contact me by email,
phone or (if you are in Konstanz even better) come to my office.

Theses in cooperation with other groups at the RWTH Aachen university and its surrounding are also highly encouraged.
