Fig. 1. UV-vis spectra of the as-synthesized colloids: (a) UV-vis absorbance of Colloid A, B, C, and D; (b) the effect of seeded growth of GNPs, curve 1 shows the absorbance with hydroxylamine hydrochloride as reducing agent in HAuCl4 solution, curve 2 is the absorbance with THPC, and curve 3 shows the reduction by hydroxylamine hydrochloride with addition of Colloid A. Inset: enlarged absorbance peak of curve 1.
