Inside Cover: Silver Nanocrystals with Concave Surfaces and Their Optical and Surface-Enhanced Raman Scattering Properties (Angew. Chem. Int. Ed. 52/2011)
A seed-mediated growth method has been used to synthesize silver nanocrystals enclosed by concave surfaces and thus high-index facets in aqueous solution. Y. Xia and co-workers report in their Communication on page 12 542 ff. that controlling the growth habit of silver cubic seeds leads to concave silver nanocrystals that act as surface-enhanced Raman-scattering substrates with stronger signal enhancements than conventional silver nanocrystals of a similar size but enclosed by flat faces.
