Cover Picture: Selective Detection of Ethylene Gas Using Carbon Nanotube-based Devices: Utility in Determination of Fruit Ripeness (Angew. Chem. Int. Ed. 23/2012)
Ethylene is the smallest ripening hormone in plants. In their Communication on page 5752 ff., T. M. Swager et al. show that from a simple mixture of single-walled carbon nanotubes and a copper(I) complex, chemoresistive devices can be prepared that are highly sensitive and selective to sub-ppm concentrations of ethylene. The utility of the sensor was demonstrated by following ripening stages in different fruits.

In cysteine-rich peptides, diselenides can be used as a proxy for disulfide bridges. G. Bulaj et al. describe in their Communication on page 5580 ff. how an intramolecular diselenide bond catalyzes the oxidative folding of selenopeptide analogues of conotoxins.
The self-assembly of a colloidal metal–organic framework through simple capillary and van der Waals attractions is described by S. Granick and N. Yanai in their Communication on page 5638 ff.
In their Communication on page 5634 ff., T. S. Seo, S. Y. Lee, and co-workers demonstrate the synthesis of homogeneous biogenic paramagnetic nanoparticles inside recombinant E. coli cells by encapsulating them in nanoliter-scale droplets.
