Directed Assembly of Three-Dimensional Microvascular Networks
The construction of 3-D microvascular networks enables microfluidic devices with unparallel geometric complexity. In one example, a 3-D microfluidic mixing device was demonstrated with square-spiral mixing towers isolated within the vascular network by a secondary photopatterning process. These vertical towers give rise to chaotic advection of the fluid streams and dramatic improvements in mixing relative to simple straight (1-D) and square-wave (2-D) channels while significantly reducing the device planar footprint.
