Lateral trapping of DNA inside a voltage gated nanopore
Thomas Töws, Peter Reimann
The translocation of a short DNA fragment through a nanopore is addressed when the perforated membrane contains an embedded electrode. Accurate numerical solutions of the coupled P…
Reluctance of a neutral nanoparticle to enter a charged pore
Sebastian Getfert, Thomas Töws, Peter Reimann
We consider the translocation of a neutral (uncharged) nanoparticle through a pore in a thin membrane with constant surface charge density. If the concomitant Debye screening layer…
Opposite translocation of long and short oligomers through a nanopore
Sebastian Getfert, Thomas Töws, Peter Reimann
We consider elongated cylindrical particles, modeling e.g. DNA fragments or nano-rods, while translocating under the action of an externally applied voltage through a solid state n…
Single-molecule force spectroscopy: Practical limitations beyond Bell's model
Sebastian Getfert, Mykhaylo Evstigneev, Peter Reimann
Single-molecule force spectroscopy experiments, as well as a number of other physical systems, are governed by thermally activated transitions out of a metastable state under the a…
Spontaneous Ratchet Effect in a Granular Gas
Devaraj van der Meer, Peter Reimann, Ko van der Weele +1
The spontaneous clustering of a vibrofluidized granular gas is employed to generate directed transport in two different compartmentalized systems: a "granular fountain" in which th…
