Stretching experiments with long double-stranded DNA molecules in physiological ambient revealed a force-induced transition at a force of 65pN. During this transition between B-DNA and highly overstretched S-DNA the DNA lengthens by a factor of 1.7 o

P-pili of uropathogenic Escherichia coli mediate the attachment to epithelial cells in the human urinary tract and kidney and therefore play an important role in infection. A better understanding of this mechanism could help to prevent bacteria from

Atomic force microscope (AFM) single molecule force spectroscopy has been used to investigate the friction coefficient of individual polymers adsorbed onto a solid support. The polymer chains were covalently attached to an AFM tip and were allowed to

Polymers play a central role in cantilever-based single molecule force spectroscopy, either as sample or as anchor of the molecular complexes under investigation. Here we investigated the role of the polymer for the coupling of thermal and mechanical

Dynamic force spectroscopy is a valuable technique to explore the energy landscape of molecular interactions. Polymer spacers are typically used to couple the binding partners to the surfaces. To illustrate the impact of polymer spacers on the measur

DNA displays a richness of biologically relevant supramolecular structures, which depend on both sequence and ambient conditions. The effect of dragging double-stranded DNA (dsDNA) from water into poor solvent on the double-stranded structure is stil

Progress in scanning probe microscopy profited from a flourishing multitude of new instrument designs, which lead to novel imaging modes and as a consequence to innovative microscopes. Often these designs were hampered by the restrictions, which conv

In this paper, we measure the single chain elasticity of an oligomer single-stranded DNA (ssDNA) in both aqueous and nonaqueous, apolar liquid environments by AFM-based single molecule force spectroscopy. We find a marked deviation between the force-

The end-to-end distance and the contour length of single polymers in dynamic adsorbate layers were measured with a mechanical approach. Individual polysaccharide chains were covalently pinned to the surface with one segment and picked up randomly wit
