Polymer- and salt-induced toroids of hexagonal DNA

Article, Other literature type English OPEN
Ubbink, J; Odijk, T;

A model is proposed for polymer- and salt-induced toroidal condensates of DNA, based on a recent theory of the undulation enhancement of the electrostatic interaction in the bulk hexagonal phase of semiflexible polyions. In a continuum approximation, the thermodynamic p... View more
