Multifunctional Bio-Nano Patterns Derived from Colloidal Self-Assembly as Model Surfaces to Study Antigen-Antibody Interactions

Krishnamoorthy S., Wright J.P., Worsfold O., Fujii T., Himmelhaus M., Fujirebio Inc., JP

Nanosphere lithography (NSL) has become a popular tool as a patterning technique recently because the method is cheap and involves extremely simple procedures compared with other nanopatterning techniques. NSL can also be applied to a [...]

Nano-Patterned Surfaces Enhance Immunoreaction Efficiency

Valsesia A., Mannelli I., Colpo P., Bretagnol F., Ceccone G., Rossi F., European Commision Joint researcc Center, IT

Biomolecular recognition is a fundamental aspect in the biosensor development. The goal is to immobilize the biomolecule probes in an active state, limiting the non specific adsorption and maximizing their binding site accessibility for the [...]

Manufacturable nanoscale membranes – material development and biological separations

Gaborski T.R., Striemer C.C., Snyder J.L., Fang D.Z., Fauchet P.M., McGrath J.L., University of Rochester, US

We have developed a new class of ultrathin porous nanocrystalline silicon (pnc-Si) membranes using inexpensive and scalable silicon fabrication techniques. Pnc-Si is formed from a deposited amorphous silicon thin film, where nanoscale pores are introduced [...]

From Particle Self-Assembly to the Creation of Biologically Relevant Nanopatterns

Blättler T.M., Binkert A., Reimhult E., Textor M., Vörös J., ETH Zürich, CH

Nanopatterns are becoming increasingly popular in the field of bioscience and bioengineering because they provide novel tools to address biological problems. For example, protein nanoarrays not only enable molecular level statistics of binding events but [...]

Low Temperature Nanolayers of Metal Oxides By MVD

Kobrin B., Dangaria N., Chinn J., Applied Microstructures, Inc., US

Molecular Vapor Deposition (MVDTM) techniques and equipment have been successfully used for many coating applications in the MEMS, disk drive, and nano-imprint lithography fields. By exploiting the ability of MVD to deposit an in-situ metal [...]

The Si-tag for Immobilizing Proteins on a Silicon Device

Kuroda A., Hiroshima University, JP

Targeting functional proteins to specific sites on a silicon device is essential for the development of new biosensors and supramolecular assemblies. Recently, we found ribosomal protein L2 as a silicon-binding protein, which can be used [...]

Utilizing PRINTTM Technology to Create Precision Nanopatterned Films

Denison Rothrock G., Rolland J., Henn R., Liquidia Technologies, US

We describe the use of a new, enabling class of materials for performing precise, nano-scale imprint lithography for patterned film replication. These low surface energy, minimally adhesive, room-temperature photocurable perfluoropolyether (PFPE) elastomers, trademarked as Liquidia’s [...]

Nanoscale hydrophobic coatings for the separation of liquid mixtures

Truman P., Frenzel R., Longari N., Uhlmann P., Stamm M., Institute of Polymer Research, DE

Organofunctional nanoscale silane coatings are widely used to modify surface chemistry. Such coatings have many applications in micro- and nanofluidics because liquid motion on these scales is strongly influenced by capillary or wall effects. In [...]

Single Election Trapping in Nanoscale Transistors; RTS(Random Telegraph Signals) and l/f Noise

Forbes L., Miller D.A., Louie M.Y., Oregon State University, US

Random telegraph signal, RTS, noise[1] is most obvious in submicron devices with traps, for example in nanoscale MOS transistors, MOSFET’s, with a low number of carriers. RTS is sometimes an indicator of poor device quality [...]

Quantum Correction for the Current-Based One-Particle Monte-Carlo Method

Brugger S.C., Wirthmueller A., Schenk A., ETH Zürich, CH

In a previous work we proposed a one-particle Monte-Carlo method based on equations for the currents. Our method has the advantage of being able to take into account arbitrary generation-recombination processes self-consistently. Recently, we extended [...]
