The characterization of MPDA. A, BÂ FE-SEM images and (C, D) TEM images of MPDA particles. High magnification SEM images in B and TEM images in D showed typical MPDA particles. Inset in A showed corresponding size distribution histograms and theoretical fitting of MPDA particles. E Dark field TEM and energy-dispersive X-ray spectroscopy-based elemental mapping analysis of MPDA particles. Scale bars were indicated by lines in the figures
