Cover Picture: Highly Stereospecific Generation of Helical Chirality by Imprinting with Amino Acids: A Universal Sensor for Amino Acid Enantiopurity (Angew. Chem. Int. Ed. 45/2008)
A spiral staircase follows the many helical structures in nature. J.-I. Hong, H.-J. Kim, J. Chin, and co-workers describe how amino acids induce helicity with hydrogen bonding into a 2,2'-dihydroxybenzophenone derivative in their Communication on page 8657 ff. Signaling groups can be added to allow the receptors to sense amino acid enantiopurity.

Gadolinium Contrast Agents
In the Minireview on page 8568 ff., K. N. Raymond and co-workers discuss the parameters that should be optimized in the development of gadolinium chelate complexes as contrast agents for magnetic resonance imaging.
E. Magner and co-workers discuss in their Review on page 8582 ff., the requirements necessary to introduce proteins into the pores of mesoporous solids and to anchor them there. How catalytically active are such immobilized proteins?
An iron(II) spin-transition compound can be nanopatterned to give crystalline and well-oriented structures. Potential applications are also described by M. Cavallini, M. Ruben, and co-workers in their Communication on page 8596 ff.
