Light-enhanced microcontact printing of 1-alkynes onto hydrogen-terminated silicon.
نویسندگان
چکیده
A method for the direct patterning of 1-alkynes onto hydrogen-terminated silicon is presented. It combines microcontact printing with illumination through the stamp, and results in the formation of an alkenyl monolayer. The formation of heterogeneous monolayers is demonstrated by subsequent backfilling.

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...
متن کاملSilicon microcontact printing engines
A method of self-aligned, microcontact printing that avoids the need for dedicated alignment and stamping equipment is demonstrated. Complete miniature print engines combining elastically supported print heads with alignment structures that mate with corresponding features on etched substrates to allow mechanical registration are constructed from silicon parts. The impression can be transferred...
متن کاملCreating patterned carbon nanotube catalysts through the microcontact printing of block copolymer micellar thin films.
We report a route for synthesizing patterned carbon nanotube (CNT) catalysts through the microcontact printing of iron-loaded poly(styrene-block-acrylic acid) (PS-b-PAA) micellar solutions onto silicon wafers coated with thin aluminum oxide (Al(2)O(3)) layers. The amphiphilic block copolymer, PS-b-PAA, forms spherical micelles in toluene that can form quasi-hexagonal arrays of spherical PAA dom...
متن کاملMicrocontact Printing of Proteins for Cell Biology
The ability to pattern proteins and other biomolecules onto substrates is important for capturing the spatial complexity of the extracellular environment. Development of microcontact printing by the Whitesides group (http://gmwgroup.harvard.edu/) in the mid-1990s revolutionalized this field by making microelectronics/microfabrication techniques accessible to laboratories focused on the life sci...
متن کاملCombinatorial Method for Surface-Confined Sensor Design and Fabrication
The procedure for the combinatorial fabrication of new sensing materials for cations and anions based on self-assembled monolayers (SAM) is discussed. A library of different sensitive substrates is generated by sequential deposition of fluorophores and small ligand molecules onto an amino-terminated SAM coated glass. The preorganization provided by the surface avoids the need for complex recept...
