Line Plot from Scientific Research

Variation in the absorbance at the LSPR maximum wavelength upon the addition of aqueous NaHSO3(165 mM) alone (red open symbols), aqueous HMTA (40 mM) alone (blue symbols), and both NaHSO3(165 mM) and HMTA (40 mM) in water (filled red symbols) to AuNP-1(0.16 mg mL−1). For full spectra, see Figure S7. Data showing the catalytic effect on nanoparticle dispersion of ammonium ions is shown in Figure S8.
