We have recently demonstrated the isolation and trapping of double stranded lambda-DNA in a microfluidic chip by means of electrophoresis (EP) and dielectrophoresis (DEP) [1].
The purpose of this project is to develop a fluidic chip combining micro- and nanofluidic structures with integrated electrodes in order to achieve the electrical

detection of DNA translocation (Coulter counter principle). Such device will eventually be combined with our existing microfluidic system.
