The double-sided structural color of Fe3O4@SiO2 NPs under external electric field was found.

The change of structural color was obviously observed on both sides of the display cell through an applied of electric field.

The reflection peak move backwards within a particular range of wavelength under a certain electric field.

The interacting force of Fe3O4@SiO2 NPs under the electric field was studied.
