Detecting Enzyme Activities with Exogenous MRI Contrast Agents
All with one basket: This review focuses on exogenous MRI contrast agents that are responsive to enzyme activity. Enzymes (signified by the basket in the figure) can catalyze a change in water access, rotational tumbling time, ligand proximity, aggregation state, chemical exchange rate, or the chemical shift of 19F, 31P, 13C, or a labile 1H of an agent, which can be used to detect enzyme activity. The variety of 49 agents attests to the creativity in developing enzyme-responsive MRI contrast agents. [Review]

Angewandte Chemie 31/2014: Sizzling Hot
In this issue, many contributions are dedicated to George Whitesides on the occasion of his 75th anniversary. R. Haag et al. review protein interactions with polymer coatings and biomaterials. What are the recent developments in analytics, biochemistry, and theory beyond Teflon? In a Minireview, E. Kumacheva et al. summarize microfluidic studies of carbon dioxide. The Highlight deals with crystal structures in light harvesting and charge separation in photosynthesis (O. Einsle).
In the Communications section, T. Ohba examines size-dependent water structures in carbon nanotubes (see picture). N. L. Abbott et al. report on the change in orientation of liquid crystals anchored on monolayers of chiral versus achiral molecules. M. Hartmann and A. Studer present the cyclizing radical carboiodination, carbotelluration, and carboaminooxylation of aryl amines, and K. O. Christie et al. succeeded in the preparation of trivalent and tetravalent manganese azides.
Dating by Electrode
Voltammetry of microparticles used to date archeological artifacts made of copper and bronze
How can the age of archeological objects be determined if the well-established carbon dating method does not apply, for example for metal objects? Spanish and Portuguese scientists have now introduced a technique for dating artifacts made of copper and bronze. Presented in the journal Angewandte Chemie, their electroanalytical method is based on the voltammetry of microparticles. It compares various corrosion products that form over long periods of time and works with only a few nanograms of material so it causes almost no damage.
