Abstract:
1. A microfluidic device for separating, fractionating, or preconcentrating analytes contained in an electrolyte having at least two reservoirs separated by at least one microchannel and/or nanochannel, wherein: said at least one microchannel and/or nanochannel has a planar geometry, at least part of the upper and/or lower wall of the microchannel is made of and/or coated interiorly with a conducting and polarizable material or group of materials constituting a polarizable interface or interface network, at least one electrode or at least one electrode network is connected at at least one point of the polarizable material or group of materials, the conductive and polarizable material or group of materials has a polarizability window being at least 0.5 V for cathodic and anodic reactions, the surface electrical conductance of said interface or interface network being equal to at least 100 nS.
