Back Cover: Unconventional Chain-Growth Mode in the Assembly of Colloidal Gold Nanoparticles (Angew. Chem. Int. Ed. 32/2012)



original image

The “chain-growth polymerization” of gold nanoparticles involves their initial encapsulation by polystyrene-block-poly(acrylic acid) and the self-assembly of the resulting “monomers” into long chains of up to 300 nanoparticles. In their Communication on page 8021 ff., H. Chen et al. state that the nanoparticle assembly is highly selective and gives chains with uniform width and interparticle spacing. The background of the picture shows the skyline of Singapore.
