Figure 3. 3D reconstruction and quantitative analysis. (A) Orthogonal slices, 3D volume, and 3D sectioned views of MNPs@ZIF-8 samples exhibit intact ZIF-8 shells with clearly distinguishable MNPs; (B) Classification of aggregated and encapsulated MNPs; (C) NND distribution and RD analysis to characterize specific dispersion patterns and radial distribution features, respectively. NND: Nearest-neighbor distance; RD: radial distribution; MNPs@ZIF-8: metal nanoparticles encapsulated within zeolitic imidazolate framework-8.
