Gold nanoparticle characterization. (a) Gold nanoparticles are decorated with polyethylene glycol (PEG) for improved stability and a peptide containing integrin binding domain RGD, to improve uptake into tumours. (b) The hydrodynamic diameter of the gold nanoparticles was measured using dynamic light scattering, following functionalization with PEG and RGD. (c) Scanning electron microscopy of the gold nanoparticles. Scale bar is 500 nm. (d) ζ-potential of the gold nanoparticles before and after functionalization with PEG and RGD.
