Gold nanoparticles (AuNPs) with protein

[ZhiChai]

Dear Developer,

I am planning to set up simulations of gold nanoparticles (AuNPs) interacting with proteins. I found a force field for AuNPs developed for interactions with POPC lipid membranes [https://pubs.acs.org/doi/10.1021/acs.jctc.1c00627]
), but I assume this parameterization is mainly intended for membrane systems and may not directly transfer to other lipids or to protein–AuNP interactions.

I was wondering whether a Martini force field available for AuNPs has been developed that can be used with proteins. Thank you very much for your time and assistance.
