48_15/2009Cover Picture: Compartmentalization of Chemically Separated Components into Droplets (Angew. Chem. Int. Ed. 15/2009)

Electroosmotic-flow-driven droplet generation integrated with capillary electrophoresis (CE) allows the molecular components separated by CE to be compartmentalized into a stream of droplets, as reported by D. T. Chiu and co-workers in their Communication on page 2719 ff. and illustrated on the cover picture. After separation and droplet compartmentalization, the droplet-confined bands either can be docked and studied on-chip or removed off-chip for a second-dimension separation and further analysis.
