I thought the protein would be the hard part...
In the end I would like to look at effect the nanoparticles have on
ordering the system. Thus, to the best I can see right now, I would want
the course-grain model to include a local and global approximation to the
nanoparticle's electric field and surface polarizability due to water and
the proteins. I only expect the gold nanoparticle to interact via high
order electric moments, that depend on its shape, with the proteins. Is
that way off the mark?
In the end I will be trying to replicate a colleagues experimental results
of order inducement as a function of gold nanopartcile concentration and
