A method of single‐shot imaging via aberration‐corrected scanning transmission electron microscopy equipped with high angle annular dark‐field detector (STEM‐HAADF) has been applied to size‐selected gold model catalysts (Au 25 and Au 39 ) on hydroxyapatite. Through quantitative intensity analysis, the size, in terms of number of atoms as well as 3D shape of the clusters are obtained.
