Polymer pen lithography.
We report a low-cost, high-throughput scanning probe lithography method that uses a soft elastomeric tip array, rather than tips mounted on individual cantilevers, to deliver inks to a surface in a "direct write" manner. Polymer pen lithography merges the feature size control of dip-pen nanolithography with the large-area capability of contact printing. Because ink delivery is time and force de...
متن کاملPolymer blend lithography for metal films: large-area patterning with over 1 billion holes/inch2
Polymer blend lithography (PBL) is a spin-coating-based technique that makes use of the purely lateral phase separation between two immiscible polymers to fabricate large area nanoscale patterns. In our earlier work (Huang et al. 2012), PBL was demonstrated for the fabrication of patterned self-assembled monolayers. Here, we report a new method based on the technique of polymer blend lithograph...
متن کاملMulti-color polymer pen lithography for oligonucleotide arrays.
Multi-color patterning by polymer pen lithography (PPL) was used to fabricate covalently immobilized fluorophore and oligonucleotide arrays with up to five different components. The oligonucleotide arrays offer a virtually unlimited inventory of orthogonal binding tags for self-assembly of proteins as demonstrated by use of the arrays to monitor cell-protein interactions of MCF7 cells.
متن کاملMatrix-assisted polymer pen lithography induced Staudinger Ligation.
The Staudinger Ligation has been combined with Polymer Pen Lithography to create patterns of fluorescent and redox-active inks with 1-micrometer scale feature diameters over centimeter-scale areas. This report presents a straightforward strategy to expand the scope of organic reactions employed in surface science.
متن کاملBubble-Pen Lithography.
Current lithography techniques, which employ photon, electron, or ion beams to induce chemical or physical reactions for micro/nano-fabrication, have remained challenging in patterning chemically synthesized colloidal particles, which are emerging as building blocks for functional devices. Herein, we develop a new technique - bubble-pen lithography (BPL) - to pattern colloidal particles on subs...
