Experimental verification of the cytotoxicity of ammonium-type ionic liquids (ILs). (a) Chemical structures of the cations. The anion was trifluoromethylsulfonylimide (TFSI), except for IL109 (fluorosulfonylimide, FSI). Those shown in red and blue colors are predicted to be toxic (viability <60%) and less toxic (viability >60%), respectively. IL273, 274, 275, 276, and 277 were not listed in the initial dataset; therefore, their cytotoxicity was not predicted. (b,c) experimentally determined viability data of the ammonium ILs at (b) 1 h and (c) 24 h. Error bars represent standard deviations of N = 3.
