چکیده

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.

Catalytic microcontact printing on chemically functionalized H-terminated silicon.

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...

Soft Lithographic Functionalization and Patterning Oxide-free Silicon and Germanium

The development of hybrid electronic devices relies in large part on the integration of (bio)organic materials and inorganic semiconductors through a stable interface that permits efficient electron transport and protects underlying substrates from oxidative degradation. Group IV semiconductors can be effectively protected with highly-ordered self-assembled monolayers (SAMs) composed of simple ...

Patterning Ligands on Reactive SAMs by Microcontact Printing

This report describes a method for patterning ligands onto mixed SAMs of alkanethiolates on gold by microcontact printing (μCP). The mixed SAMs were made from thiols presenting terminal tri(ethylene glycol) groups (HS(CH2)11(OCH2CH2)3OH, 1) and terminal hexa(ethylene glycol)-CH2CO2H groups (HS(CH2)11(OCH2CH2)6OCH2CO2H, 2). Ligands were printed using a two-step procedure. The carboxylic acid gro...

Ijsing Self-assembled Monolayers to Understand the Interactions of Man- Made Surfaces with Proteins and Cells

Self-assembled monolayers (SAMs) formed on the adsorption of longchain alkanethiols to the surface of gold or alkylsilanes to hydroxylated surfaces are well-ordered organic surfaces that permit control over the properties of the interface at the molecular scale. The abililty to present molecules, peptides, and proteins at the interface make SAMs especially useful for fundamental studies of prot...

Creating two-dimensional patterned substrates for protein and cell confinement.

Microcontact printing provides a rapid, highly reproducible method for the creation of well-defined patterned substrates.(1) While microcontact printing can be employed to directly print a large number of molecules, including proteins,(2) DNA,(3) and silanes,(4) the formation of self-assembled monolayers (SAMs) from long chain alkane thiols on gold provides a simple way to confine proteins and ...
