Summary: Ionic liquids (ILs) are currently attracting researchers due to their potential applications in various fields. In biomedical research, understanding the interactions between ILs and cellular membranes, mimicked with lipid bilayers and monolayers, is crucial. Among the three imidazolium-based ILs studied, [DMIM][BF4] showed the strongest interaction with liver lipid membranes. This interaction is mainly driven by entropy and results in ILs penetrating the core of lipid bilayers. Dynamic light scattering (DLS) measurements suggest that [DMIM][BF4] does not affect the stability of lipid vesicles, while X-ray reflectivity (XRR) measurements reveal a concentration-dependent change in monolayer structure.
