Peptide-mediated assembly. TEM images showing the different structures obtained for AgNPs-BSPP that reacted for 15 min with different concentrations of RRK: (A) 0 nM, (B) 150 nM, (C) 250 nM, (D) 400 nM, and (E) 1 μM. (F) Deformation of the UV–vis spectrum of AgNPs-BSPP 15 min after the addition of different concentrations of RRK from 0 nM to 10 μM (the arrow indicates the increase of peptides added) and (G) the corresponding pictures. (H) Evolution of the assembly intensity (Abs.600 nm/Abs.400 nm) over time for different concentrations of RRK added to AgNPs-BSPP. Evolution of the assembly intensity as a function of the peptide concentration for (I) arginine-based, (J) histidine-based, or (K) phenylalanine-based peptides.
