and the two side channels. Three-dimensional focusing is achieved when one incoming
stream is vertically focused by two others [80-85].

4.2.3.2 Split-and-Recombine Micromixers

In the creeping laminar flow regime (Re 10), split-and-recombine (SAR) micromixers

rely on the same principle as do multilamination mixers, yet they differ in the fact that they
incorporate flow splitting,

recombination and rearrangement (Figure 4.5). Using
