Identification and localization of yttria NPs. (a) One reconstructed digital slice from 12 h-fed mealworm sample scanned using 17.3 keV X-rays, above the yttrium K-edge energy. (b) The same slice scanned at 16.7 keV, below the Y K-edge. (c) K-edge subtraction image, obtained by the subtraction of the 16.7 from 17.3 keV slice. (d, e, f) Enlarged areas showing aggregates of yttria NPs (circled) and the image artifacts due to sample motion or tissue shrinkage that can be excluded from identification as NPs (arrows).
