Fig. 4From: Characterization of Conventional One-Step Sodium Thiosulfate Facilitated Gold Nanoparticle SynthesisSeed-mediated growth of gold-gold sulfide nanoparticles. Seed-mediated growth of particles resulted in suppression and blue-shifting of the NIR peak. Corresponding TEM image shows predominantly icosahedral particles with reduced nanoplate formation and size (<50 nm) as compared with conventional one-step synthesis. Scale bars represent 200 nmBack to article page
