Abstract
A micro-reactor is provided with a mixture of channels having larger cross-sectional areas (') and channels having smaller cross-sectional areas (′). The smaller channels (′) resist liquid movement driven by hydrostatic force but allow liquid movement driven by electro-osmotic force. Accordingly liquid flow is almost entirely driven by electro-osmotic force. The smaller channels (′) are formed by etched grooves which are closed by a planar surface. This allows the cross-sectional areas of the smaller channels to be closely and reproducibly controlled.
