51_17/2012Cover Picture: Oligoprolines as Scaffolds for the Formation of Silver Nanoparticles in Defined Sizes: Correlating Molecular and Nanoscopic Dimensions (Angew. Chem. Int. Ed. 17/2012)

Functionalized oligoproline scaffolds that have defined lengths have been shown to control the size of silver nanoparticles that are formed in the Tollens reaction. In their Communication on page 4231 ff., H. Wennemers et al. demonstrate the correlation between the molecular dimensions of the peptide scaffold and the size of the nanoparticles that are produced in an approach that opens the door to precise control of the size of metal nanoparticles.
