Fig. 7From: Characterization of Conventional One-Step Sodium Thiosulfate Facilitated Gold Nanoparticle SynthesisMicrofiltration process of polydisperse samples. Samples of interest, species B and C were collected via sequential filtration steps. Species B includes all particles retained by the 0.1-μm filter. Species C contains particles which passed through the 0.05-μm filterBack to article page
