48_29/2009Cover Picture: A Microfluidic Approach to Chemically Driven Assembly of Colloidal Particles at Gas–Liquid Interfaces (Angew. Chem. Int. Ed. 29/2009)

A chemically mediated microfluidic approach to the generation of particle-coated bubbles is reported by E. Kumacheva and co-workers in their Communication on page 5300 ff. The approach employs rapid, controllable dissolution of CO2 bubbles in a dispersion of carboxylated particles. Local increases in the acidity of the medium in the neighborhood of the bubbles lead to a change in the surface energy of the particles and their deposition on the gas–liquid interface.

T. Sun, L. Chi and co-workers describe in their Communication on page 5282 ff. how plasmid DNA prefers relaxed conformations on a surface modified with l-N-isobutyrylcysteine (l-NIBC), whereas the supercoiled conformation is more likely on the d-NIBC surface. Picture design: J. Zhao.

A reaction delivering optically active amines with 98 % ee using an iridium(I) catalyst is described by K. Ding and co-workers in their Communication on page 5345 ff. The catalyst system was used in the synthesis of sertraline, an important antidepressant.
