Effect of increasing chloroauric acid concentrations on nanoparticle spectral profile. UV-visible spectra of gold nanoparticles with increasing chloroauric acid concentrations from 0.02 to 0.05 mM in 0.01 mM increments, from 0.1 to 0.5 mM in .1 mM increments, and at 1 mM. The inset is the absorbance spectra of gold nanoparticles produced from concentrations of 0.02 to 0.1 mM.
