This image demonstrates results of a study of microstructure formation in polymers that self-assemble into different shapes ranging from grains to lines, and that are interconnected into complex patterns and meshes. Pictured is the microstructure of a 2-millimeter-long fragment of self-assembled polymers, which materials scientists are using to build miniature "lab-on-a-chip" devices for biomedical diagnostic applications.
