The distinct effects of two imidazolium-based ionic liquids, [C ₄ mim][OAc] and [C ₆ mim][OAc], on the phase behaviours of DPPC

mim][OAc], it could eliminate the pre-transition of DPPC, markedly affect the main phase transition of the lipid, and insert into the DPPC bilayer at gel state to form an interdigitated gel phase. The findings increased our understanding on the biological effects of imidazolium-based ILs and might shed light on the design of novel IL-based antimicrobials.
