Figure 10.

Overlapped spectra of the elemental mapping of nanoMIL-89. PAECs were treated with 3µg/mL (blue line) and 5µg/mL (red line) of nanoMIL-89, respectively. (A) showing the full spectra of elements signal (cps/eV) with respect to energy signal (keV), zoomed in (B) to show the L⍺ Fe signal (≈0.705 keV) and in (C) to show the K⍺ Fe signal (≈6.398 keV) for both samples. The intracellular iron signal was measured using Bruker EDS installed in a Talos TEM system.
