title: Catalytic microcontact printing on chemically functionalized H-terminated silicon.
abstract: We report a novel inkless soft lithographic fabrication protocol that permits uniform parallel patterning of hydrogen-terminated silicon surfaces using catalytic elastomeric stamps. Pattern transfer is achieved catalytically via reaction between sulfonic acid moieties covalently bound to an elastomeric stamp and a Boc-functionalized SAM grafted to passivated silicon. The approach represents the first example of a soft lithographic printing technique that creates patterns of chemically distinctive SAMs on oxide-free silicon substrates.
