Droplet attraction: Surfactants responsive to magnetic fields are reported for the first time. This new class of magnetic ionic liquid surfactants (MILSs; see picture) shows remarkable effects on surface and interfacial tension and allows access to magneto-responsive emulsions and new methods of separation, recovery, catalysis, and potential magnetophoretic applications.
