Assembly characterization. (A, B, and C) EDX elemental mapping of AgNPs-BSPP after the reaction with 1 μM RRK showing the (B) silver and (C) carbon composition of the material. (D) Crystal structure of AgNPs-BSPP (I) before and (II) 30 min after the reaction with 1 μM RRK obtained by XRD. (E, F, G, and H) Multispectral advanced nanoparticle tracking analysis (MANTA) images of the AgNPs- BSPP (E) before or (F) 5 min and (G) 15 min after the addition of 1 μM RRK showing the size evolution and (H) the corresponding size distribution. (I, J, K, L, M, and N) TEM images showing the evolution of the assembly of AgNPs-BSPP upon the addition of 1 μM RRK at 4°c
