(a) Difference and (b) DSC (image of various sized polystyrene nanoparticles. Scalebar is 1 µm. Some of the particles visible in the DSC image are not detectable in the difference image (c) SEM image of the same region and zoomed in version. (d) Lineprofiles along the dashed lines shown in (a) and (b), for difference image and DSC image respectively.
