Introduction


Nucleic acids pass through membranes in several biological processes, e.g.

Artificial Translocation through Nanopores (rapid sequencing of DNA?)

The translocation of the DNA molecules can be stalled by switching off the electrical field during their passage.

The unbiased dynamics of the molecules can then be followed.
