Relation between surface charge and the flow rate within microfluidic channels

Abstract

I created a highly adaptable, easy-to-make microfluidic cell, in which one can change the flow rate via a pressure-driven flow. By using electro-osmotic flow, which relates to the surface charge of a channel, I looked at the relation between surface charge of the channel and the flow rate. The literature suggests that there is a causal relation. I created a proper method to research this, and found that there is indeed a (mostly) linear relation between the two.
