  • Title: Asymmetric bridging of interconnected pores by encased semiflexible macromolecules.
    Author: Cifra P.
    Journal: J Chem Phys; 2006 Jan 14; 124(2):024706. PubMed ID: 16422625.
    Abstract:
    An increase of chain rigidity of macromolecule encased in interconnected cavities leads to bridging conformational transition in which polymer molecule at certain conditions spans the cavities. This is a similar phenomenon to that described for flexible chains on increase of confinement. Chain stiffness introduces, however, a delicate effect of interplay between confinement, chain stiffness, and concentration that leads to a breakup of symmetric bridging conformation to a striking asymmetric conformation even in the symmetric system of cavities. We provide the first data on this transition with complex translocation landscape and offer a tentative explanation.
