Semiflexible polymer condensates in poor solvents: toroid versus spherical geometries

Miller, I; Keentok, M; Pereira, Gerald George; Williams, David


Semiflexible polymers, such as DNA, in the presence of a condensing agent often form toroids. This is due to a balance between bending and surface area free energy penalties. Here we show why in experiments all the toroids have been found to have similar physical size. We also introduce a novel morphology, that of the hollow sphere, which is favored for long polymer chains. This offers the possibility of encapsulating material inside a “vesicle” made of semiflexible polymers. We also consider...[Show more]
