Figure 6From: Mono- and bi-functional arenethiols as surfactants for gold nanoparticles: synthesis and characterization Bright field TEM images of benzylthiol-gold nanoparticles prepared with Au/S molar ratio 15:1 (A4) taken with different magnification. The particle agglomeration is well pronounced (a) and only very few isolated particles can be observed (b, c). The average particle size is about 9 nm (c).Back to article page
