Fig. 2 — Characterization of ligand-free AuNPs and AuNP-CPP agglomerates. a Hydrodynamic diameter of ligand-free AuNPs and AuNP-NLS agglomerates (both stabilized with BSA) determined by dynamic light scattering. b Particle number distributions of agglomerated (NLS-conjugated) and primary, ligand-free AuNPs obtained from TEM-images. Representative images are depicted in the insets (scale bars: left 50 nm, right 20 nm)
