Cover Picture: Single DNA Molecule Isolation and Trapping in a Microfluidic Device (ChemPhysChem 12/2007)
The cover picture shows a single DNA molecule trapped between floating aluminium electrodes by means of alternating current dielectrophoresis. The image was obtained by fluorescence microscopy using double-stranded lambda-phage DNA labelled with the YOYO-1 fluorescent dye. In their Article on page 1875 Kumemura et al. describe a method enabling the isolation and trapping of single DNA molecules in a microfluidic chip by using consecutively direct current electrophoresis and alternating current dielectrophoresis.
