We demonstrate nanometer displacements of quantum dots placed on top of polymer bilayers that undergo swelling when changing from an air to a water environment, achieving standard deviations below 10 nm for axial and lateral localization.MicorscopyFluorescence microscopySpectroscopytext::journal::journal article::research article
