| Abstract: | We have investigated the phase behaviour of pUC18 plasmid solutions with
phase separation experiments and polarized light microscopy. Furthermore,
the configuration of the superhelix is monitored with small-angle neutron
scattering. The phase diagram is interpreted with liquid crystal theory including
the effects of charge, orientation entropy, excluded volume, as well as the elastic,
entropic and electrostatic contributions to the molecular free energy. |
