Nicotinium-based surface-active ionic liquids as antimicrobial surfactants: Micellization properties, antibiofilm activity, and biocompatibility.
A new family of nicotinium-based surface-active ionic liquids (CₙNicBr, n = 10-16) was synthesized by N-alkylation of nicotine and characterized by NMR, MS and thermogravimetry (stable to 215 °C). Aqueous association, assessed by conductimetry, fluorescence, tensiometry and dynamic light scattering, gave critical micel...
