(A) The homemade flow cell used in the electrophoresis experiments. To assemble the apparatus, a patterned SLB on a glass cover slip is seated between a steel plate and an observation window. SLB fluorescence is observed from below through the observation window by epifluorescence microscopy. (B) 5 distinct regions of resistance inside the flow cell that correspond to the cross sectional area above each location.
