Micro-molding in capillaries

Micro-molding in capillaries (MIMIC) represents another form of RM. In MIMIC, a patterned polymeric mold is placed into conformal contact with a surface to form a network of empty channels. When a low-viscosity photocurable fluid (such as PU) is placed at the open ends of the channels, the liquid spontaneously fills the channels by capillary action. After the PU is cured under UV light, the mold is removed to leave behind a network of polymeric features. Although MIMIC is a remarkably simple technique and transfers features with high fidelity, it is limited by the viscosity of the liquid precursors that can fill the channels. Channels having dimensions smaller than 100 nm are difficult to fill by capillary action. Figure 7 illustrates the general process of MIMIC.
