Microcontact printing of octadecylsiloxane on the surface of silicon dioxide and its application in microfabrication
- Harvard Univ., Cambridge, MA (United States)
This paper describes the use of microcontact printing ({mu}CP) for patterning self-assembled monolayers (SAMs) of alkylsiloxanes on the surface of silicon dioxide. {mu}CP is a convenient technique for generating patterned SAMs of alkanethiolates on gold, but it has not been applied to Si/SiO{sub 2} and glass. The SAMs of alkyltrichlorosilanes on the hydroxyl-terminated surfaces are less ordered than those of alkanethiolates on gold, and they form more slowly. Here we demonstrate that {mu}CP can, nonetheless, be used to produce patterned SAMs of alkylsiloxanes on Si/SiO{sub 2}. We believe this technique will prove valuable for many other applications: for example, studies of protein absorption and cell attachment where high edge resolution is not critical. 17 refs., 2 figs., 1 tab.
