Intact transfer of layered, bionanocomposite arrays by microcontact printing.

Patterning and Composition Arrays of Supported Lipid Bilayers by Microcontact Printing

Fluid-supported lipid bilayers self-assemble on glass and SiO2 surfaces. We have found that it is also possible to assemble fluid bilayers on plasma-oxidized polydimethyl siloxane (PDMS) surfaces. Furthermore, it is possible to transfer or print the supported bilayer from raised PDMS surfaces, such as are typically used for microcontact printing, to fresh glass surfaces creating a supported bil...

Direct microcontact printing of oligonucleotides for biochip applications

BACKGROUND A critical step in the fabrication of biochips is the controlled placement of probes molecules on solid surfaces. This is currently performed by sequential deposition of probes on a target surface with split or solid pins. In this article, we present a cost-effective procedure namely microcontact printing using stamps, for a parallel deposition of probes applicable for manufacturing ...

Microcontact printing of DNA molecules.

The controlled placement of DNA molecules onto solid surfaces is the first step in the fabrication of DNA arrays. The sequential deposition of tiny drops containing the probe DNA fragments using arrays of spotting needles or ink jet nozzles has become a standard. However, a caveat of liquid spotting is the drying of the deposited drop because this creates the typical inhomogeneities, i.e., rims...

Direct transfer of preformed patterned bio-nanocomposite films on polyelectrolyte multilayer templates.

Microarrays containing multiple, nanostructured layers of biological materials would enable high-throughput screening of drug candidates, investigation of protein-mediated cell adhesion, and fabrication of novel biosensors. In this paper, we have examined in detail an approach that allows high-quality microarrays of layered, bionanocomposite films to be deposited on virtually any substrate. The...
