Integrated Channel Selector for Directing Fluid Flow Using Thermoreversible Gelation Controlled by a Digital Mirror Device

Figure 6

Flow control for a more flexible route from the inlet to an outlet. (a) The expected route (arrow) and required gelation points (darkened areas). (b) The IR laser irradiation pattern represented as white polygons. Each polygon is a combination of two-nine squares, representing that the irradiation beam at that point was reflected by two-nine micromirrors. (c) Fluorescence image of the trajectory of the fluorescent microbead indicating that heat-induced gelation worked well to block and change the direction of fluid flow at each point.
