Biological Molecules and Carbon Nanotubes
We have been studying the structure and electrostatics of these DNA-carbon nanotube hybrids, and how they behave as colloidal particles. We have also become interested in DNA and carbon nanotube mechanics, and Poisson-Boltzmann electrostatics.

Deformation and adhesion of carbon nanotubes can be modelled accurately using elastica theory.

We have applied the J-integral to obtain exact results for the electric field near edges in an electrolyte solution.
