Abstract: | Microcontact printing (μCP) is a rapid, inexpensive way to create microscale chemical or biochemical patterns on a target surface. This microstamping method can be used to selectively modify a wide array of surface properties, from wettability and protein adsorption to chemical etch susceptibility. However, controlling the absolute location of features created with microcontact printing is difficult; this lack of precision makes it challenging to integrate with other microfabrication methods or to create complex, multi-chemical patterns on a single surface. In this research, we demonstrate a novel method of controlling the placement of microcontact printing stamps by using an integrated kinematic coupling device. This technique relies on mechanical reference points for rapid, optics-free registry of the stamp and allows μCP stamps to be quickly removed and replaced or even exchanged with submicron repeatability. |
