A multicolor fluorescent peptide–nanoparticle scaffold: real time uptake and distribution in neuronal cells

We report an elegant, facile and green protocol for designing dendrimer-like assemblies of multicolor fluorophore-labeled peptides grafted on AuNPs. The distribution pattern of these fluorescent nanoparticles in neuroblastoma cells is studied to demonstrate their use as endosome markers and further extension to multicolor imaging.
