SXRF elemental map (Fe) and the corresponding HE stain of three groups: control [(a) element map, (b) HE stain], non-targeting [(c) element map, (d) HE stain] and targeting [(e) element map, (f) HE stain; the circles are bubbles trapped during the coverslipping procedure]. The transmission images of the HE stain are magnified 100× and the scale bars in the HE stain images represent 200 µm. |
