Inkless microcontact printing on SAMs of Boc- and TBS-protected thiols

Nano Lett. 2010 Jan;10(1):43-6. doi: 10.1021/nl902588d.

Abstract

We report a new inkless catalytic muCP technique that achieves accurate, fast, and complete pattern reproduction on SAMs of Boc- and TBS-protected thiols immobilized on gold using a polyurethane-acrylate stamp functionalized with covalently bound sulfonic acids. Pattern transfer is complete at room temperature just after one minute of contact and renders sub-200 nm size structures of chemically differentiated SAMs.
