STEM XEDS line scanning through a nanoparticle found in human kidney. (a) Dark-field scanning transmission electron microscopy image of a nanoparticle found in human kidney. Insets depict 2D XEDS mapping of the precipitate for gadolinium, oxygen, and phosphorus. Calibration bars = 50 nm. (b) XEDS line scan data through the nanoparticle in A showing background corrected X-ray counts as a function of distance along the line scan.
