Manipulating DNA Conformation Using Intertwined Conducting Polymer Chains

In the field of inherently conducting polymers, polyaniline (Pani) has elicited tremendous interest due to its promising electrical properties and unique redox tunability. Synthetic routes involving the use of polyelectrolytes have significantly improved the processability of polyaniline. Recently, a template guided synthesis catalyzed by an enzyme, horseradish peroxidase (HRP), has provided a ...

The conformation of conducting polymer chains: Hubbard polymers

The conformational and electronic properties of conducting flexible random and self-avoiding polymer chains are under investigation. A Hamiltonian for conjugated flexible polymers is introduced and its physical consequences are presented. One important result is that the electronic degrees of freedom greatly affect the conformational statistics of the walks and vice versa. The electronic degree...

Equilibrium conformation of polymer chains with noncircular cross section.

In this paper we derive the general equilibrium equations of a polymer chain with a noncircular cross section by the variation of the free energy functional. From the equilibrium equation of the elastic ribbon we derive analytically the equilibrium conformations both of the helical ribbons and the twisted ribbons. We find that the pitch angle of the helical ribbons depends on the ratio of the t...

Insulated conducting polymers: manipulating charge transport using supramolecular complexes.

Rotaxane structures which provide functional insulation to conducting polymers can provide over a 4000-fold reduction in conductivity over non-rotaxane structures and with electronically active copper ions in the rotaxane units the conductivity increases by more than 80 times relative to the metal-free analog.
