(A) Statistics of aggregates populations for the targeted dimer combination Au sphere90 nm (cNP ≈ 2.17 × 1010 NP/mL) and Pd cube25 nm at different NP concentrations: I: cNP ≈ 3.49 × 1011 NP/mL; II: cNP ≈ 6.98 × 1011 NP/mL; III: cNP ≈ 1.40 × 1012 NP/mL; IV: cNP ≈ 2.09 × 1012 NP/mL. (B) Representative SEM image of the population of aggregates (scale bar 200 nm, circles highlight different classes: orange = single, yellow = dimer, green = multimer). (C) High-magnification TEM images of representative single, dimer and multimers (scale bar 50 nm).
