49_08/2010Cover Picture: Nanoparticulate Functional Materials (Angew. Chem. Int. Ed. 8/2010)

Nanoscientists boldly go to the frontiers of the smallest solids in basic science and their technical application. In their Review on page 1362 ff., H. Goesmann and C. Feldmann point to the visionary potential of nanoparticulate functional materials. After a general introduction of the topic, the optical, electrical, magnetic, and catalytic properties of nanoparticles as well as their potential for upgrading materials are summarized. Moreover, fundamentally novel shapes and compositions of matter are presented.

In their Communication on page 1402 ff., S. Grimme, G. Erker, and co-workers use a state-of-the-art theoretical analysis to determine the deciding factors in the activation of dihydrogen and other small molecules with frustrated Lewis pairs.


ATP Detectionfor003

A fluorescence-quenching process delivers spatiotemporal information of ATP in living cells. M. S. Strano and co-workers present a highly sensitive nanotube-based sensor that uses this principle in their Communication on page 1456 ff.

The stimulus-induced blue-to-red transition of polydiacetylenes (PDAs) has led to the development of a variety of PDA-based chemosensors. In their Communication on page 1422 ff., J. Yoon, J. Y. Lee, and co-workers describe an anionic-surfactant-selective sensor based on PDA and imidazolium, which shows selective color response to anionic surfactants. Furthermore, this system easily distinguishes between the anionic surfactants sodium dodecyl sulfate (SDS) and sodium dodecylbenzenesulfonate (SDBS).
