Size-dependent DNA mobility in nanochannels

Nanofluidic slits are used to investigate surface interactions during electrophoresis between DNA molecules and channel walls. The channels have vertical dimensions of 19 and 70 nm and contain no sieving matrix. Size-dependent mobility is observed for DNA in the 19 nm channels. We present a model fo...
