Fig 4. Design evolution of the 3D Micromixer.

Fig 4

Many designs were created and tested for each of the three fluidic devices (Fig 2) used in the DNA assembly experiments. Five (A-E) of 13 iterations of the Form 1+ 3D Micromixer (Fig 2B) can be seen above. Several design changes can be seen A-E: The design of the 3D micromixer was changed from a recti-linear channels with square cross-sections (A-B) similar to previous 3d micromixer designs [19,36,37], to a design using a circular cross-section and smooth curves (C-E). A mount held the initial designs (A-B); later versions (C-E) stood freely on a base. All 13 iterations are in S4 Fig
