DNA in an infinite nanochannel — •Wojciech Müller, Stefan Kesselheim, and Christian Holm — ICP, Stuttgart, Deutschland

We perform full atomistic molecular dynamics simulations, where an infinite b-DNA helix is enclosed in an infinite channel. The DNA is solvated in an explicit SPC water model, enriched with ions of various concentrations. The ion distribution and the flow is then compared to results from coarse grained models. The goal is to find the limits of these coarse grained models and identify effects which are not captured by them.
