Characterization of gold nanoparticles. a Hyper spectral imaging of gold nanoparticles decorated with polyethylene glycol (PEG) and a peptide containing RGD. Scale bar is 20 \(\upmu\)m. Inset is hyper spectral spectrum of gold nanoparticles and background. b Secondary electron image from a transmission electron microscope of gold nanoparticles. Scale bar is 300 nm. c Size of gold nanoparticles measured by dynamic light scattering while bare, with PEG, and with PEG and RGD. d Surface \(\upzeta\)-potential of bare and decorated GNPs. e Size as measured by the UV–visible absorbance spectrum of bare and decorated GNPs
