| Abstract | Models of cells and nanometer-scale biosystems are presented that
clarify their physico-chemical characteristics and allow for computer-
aided design of therapeutic and nanotechnical devices. Multiscale
techniques are used to obtain rigorous, coarse-grained equations for
the migration and structural transitions of viruses and other
bionanostructures. The theory starts with the N-atom Liouville
equation and arrives at Langevin equations for the fluctuating
dynamics of order parameters characterizing the state of major
nanoscale components (e.g., protomers, pentamers, and hexamers for
viral capsids). Application of the theory to macromolecules is also
illustrated.
A phenomenological approach is used to analyze electrical power generating bacteria. A microbial fuel cell is described in terms of a circuit diagram accounting for nanowires. These wires are self- assembled by the bacterium to mediate electron transfer processes. When the bacteria, electrodes, and substrate-bearing fluids are correctly configured, the system constitutes a bacterial fuel cell capable of directly converting organic waste into electrical power. |
