47_29/2008Cover Picture: A Reducing and Oxidizing System Minimizes Photobleaching and Blinking of Fluorescent Dyes (Angew. Chem. Int. Ed. 29/2008)

Fluorescent dyes commonly suffer from photobleaching and blinking. In their Communication on page 5465 ff., P. Tinnefeld et al. describe how reactive intermediates such as triplet and charge-separated states can be recovered by electron-transfer reactions by using a formula that contains reducing as well as oxidizing agents. Drastic improvement of the dye properties is evident in single-molecule spectroscopy.

Synthesis of Metal Oxide Nanostructuresfor001

M. Niederberger and N. Pinna show in their Minireview on page 5292 ff. how uniform metal oxide nanostructures can be prepared under exclusion of water and in the absence of surfactants.

Cellular Lifefor002

The function and sustainability of living cells depend fundamentally on size constraints. Why the evolution of nanometer-sized cell components is critical for the emergence of cellular life is described by S. Mann in his Review on page 5306 ff.

Logic Gatesfor003

In their Communication on page 5322 ff., M. E. van der Boom and T. Gupta present redox-active monolayers of osmium and ruthenium complexes on glass substrates. These monolayers, which take chemical input signals and give an optical and a chemical output, act as versatile logic gates.
