[gmx-users] Silica monolayer with Martini force field

[RAMON REIGADA SANZ]

Hi Gromacs users,

   I want to simulate a monolayer of alkane molecules attached to a solid glass surface. I wonder if anyone has experience with these kinds of systems with the Martini force field. My idea is to add water to the surface and I am interested in what happens between water and the fixed alkanes, so I will freeze the solid beads and the first carbon of the alkane chain.
My question is what kind of beads would correspond to glass (silica) surface? Somewhere I found that 'Na' beads could be used to simulate a Pt surface, but I do not know if this would work in my case.
Did anyone has experience simulating solid surfaces with Martini?

  thank you,

  Ramon
