Patterning Self-Assembled Monolayers on Oxide Surfaces Using a Lift-off Technique

A new lift-off technique for microcontact printing of thiol-terminated alkane chains on gold to oxide surfaces is presented here. The technique involves transferring the stamped pattern (the Figure shows a self-assembled monolayer of octadecylsilane) onto a silicon oxide surface, giving greater control over environmental parameters. Specific substrates are not required for the technique, which should thus be available for a wide variety of surfaces.
