What single molecules can tell us about Nano- and Biosystems — •Christoph Bräuchle — Ludwig-Maximilians-Universität München, Physikalische Chemie und Center for NanoScience, Butenandtstr. 11, D-81377 München

Single molecule studies unravel the ensemble averaging in conventional bulk experiments and allow to determine the distribution of values for an experimental parameter in heterogeneous systems rather than just giving the mean value. In addition mechanistic details show up in such experiments, which are often hidden behind the averaging process in ensemble experiments. We have applied single molecule detection techniques in nano- as well as in biosciences. The observation of the dynamics of single molecules in nanometer-sized channel and cage structures (e.g. molecular sieves) is one aspect of such investigations. The visualization of the infection pathway of a single dye-labeled virus into a living cell is another aspect of single molecule experiments in biosciences. After a general introduction the talk will concentrate on experiments in both areas.
