Fig. 3From: Variations in Spontaneous Assembly and Disassembly of Molecules on Unmodified Gold NanoparticlesDispersion and aggregation of GNP. Color Changes of GNP with different concentrations of NaCl. Both visible and UV-visible spectroscopic images are shown. Spectra are showing the changes from a blue to red shift. Shifts are indicated by red and purple spheres. An arrow indicates the direction of the shift. One optical density of GNP has been usedBack to article page
