Flow chemistry: enabling technology in drug discovery and process research.

It is difficult to predict the future of flow chemistry, but the developments mainly in the last decade indicate that much of the huge potential of this enabling technology remains to be discovered. Flow chemistry has now found its way into research and development, not only in academic institutions but also in industry. This special issue of ChemSusChem is dedicated to flow chemistry. The various contributions range from two Reviews over several Communications to a series of Full Papers. They show the large breadth of applications to which flow chemistry is the key technology.
