(a) Schematic representation of the transfer from the organic to the aqueous phase along with a photograph showing the successful transfer of OA-stabilized Fe₃O₄ M³NPs dispersed in hexane to PVP-stabilized Fe₃O₄ M³NPs dispersed in water. (b) left: TEM image of worm-like OA-stabilized M³NPs deposited from hexane dispersion; right: TEM image of PVP-stabilized M³NPs deposited from water dispersion. The insets are magnifications at 250 K.
