Resolution: standard / high Figure 4.
Hydrodynamic size from dynamic light scattering measurements and the NIR peak wavelengths. NIR peak wavelength and the hydrodynamic size of gold nanoparticles as functions
of the molar ratio of HAuCl4/Na2S2O3. (only shows samples 1 to 6 with NIR peaks in the UV–vis-NIR measurable range).
