Abstract: Linear and zigzag micro-beads were arranged by means of micro-molding in capillary (MIMIC), the mechanism of self-assembling in MIMIC was primarily studied. Annular micro-beads or semi-annual micro-beads with different numbers of microsphere were arranged through the template of the micro-droplet. When heated up to the softening temperature of polystyrene(PS) microspheres, the microspheres were joint up together. After the aluminum thin film on the substrate was dissolved, the stand-free micro-beads would be obtained. In the further study, the way linking the microsphere will be improved, so that the flexibly stand-free micro-beads can be obatined. The micro-beads can be used as a simple and direct “model” of macromolecular chain. It is hopeful to simulate condensed process of real macromolecules in a mesoscopic scale.
