(a) SIMS images of the MDA-MB-231–AuNP 2 system. 12C and 197Au elements are analyzed. (b) Series of scanned images for C and Au elements. The cell of thickness 10 µm is analyzed from the top to the bottom for seven cycles of runs. (c) Depthwise intensity profiles of C and Au elements at the positions of the squares in (a). The depth profile of the HUVEC–AuNP 2 system is displayed in the upper right corner. |
