| - | ===== Executive summary ===== | ||
| - | |||
| - | The aim of the project is to theoretically model the effects of fluctuations in Structured Coulomb | ||
| - | fluids (SCF’s) and to develop the computational means to apply implicit solvent models to | ||
| - | biological systems. | ||
| - | |||
| - | SCF’s are composed of solvated ions, charged molecules like DNA, proteins or protein | ||
| - | complexes, or larger biomolecular structures such as membranes. Since often such biological | ||
| - | systems are highly charged, both fluctuations of the electrostatic potential or electric field | ||
| - | and the nature of the polarizable surrounding medium, water, need to be taken into account | ||
| - | in order to describe these systems in a proper way. | ||
| - | |||
| - | In the first part of the project we will extend an established generalization of the mean-field | ||
| - | Poisson-Boltzmann theory of SCF’s based on the electrostatic potential to include | ||
| - | fluctuations. The second part of the project will see the development a Poisson-Boltzmann | ||
| - | theory for an SCF in terms of a local constrained functional of the electric field, which due to its | ||
| - | convexity property has an essential computational advantage and will allow applications of | ||
| - | our approach to still larger systems. | ||
