Lipid nanobubbles (LNBs) are emerging as next-generation contrast and therapeutic agents. During their interactions with cell membranes, lipids in the shell of LNBs can fuse with cell membranes. Meanwhile, the encapsulated gas molecules also have the chance to penetrate into cell membranes. However, how the fused lipids and penetrated gas molecules modulate the structure and dynamics of membrane lipids and proteins remain poorly understood at the molecular level. Molecular dynamics simulation provides a powerful computational microscopy tool for this problem. Here, I will present our recent preliminary work on developing gas force field parameters (both all-atom and coarse-grained models) and python toolkit for setting up and analyzing molecular dynamics simulations of LNBs.
