Ferrofluids are magnetic liquids interesting for the periodic patterns they form in external magnetic fields. Here, an aqueous two-phase system based on polyethylene glycol and dextran achieves an ultralow interfacial tension of ~ 1 μN m−1, resulting in micro-patterns with periodicities of ~ 200 μm.
