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.
