We present a new route for the fabrication of highly specialized miero-capillaries, based on the phenomenon of thin polymer films self-rolling. Using effects of solvent swelling or embedded stress, instability in polymer films are generated, leading to the spontaneous formation of capillaries. Before rolling, the surface can be patterned (chemically, topographically), permitting the fabrication of inexpensive fully functionalized capillaries.
