Lipid Dip-Pen Nanolithography for Functional Biomimetic Membrane Systems

Lenhert S., Forschungszentrum Karlsruhe GmbH, DE

Dip Pen Nanolithography (DPN) is uniquely well suited for the integration of multiple materials (or inks) with both high resolution and high throughput. Phospholipid-based inks are particularly well suited for this purpose for several reasons. [...]

Fabrication of biosensor arrays by DPN and multiple target detection by triple wavelength fast SERRS mapping

Stokes R.J., Dougan J.A., Stevenson R., Haaheim J., Levesque T., Faulds K., Graham D., University of Strathclyde, UK

We have used Dip-Pen Nanolithography (DPN) to create biosensor arrays on micro- and nano-structured surfaces. Bespoke linker and labelling materials enables detection of biological molecules by surface enhanced resonance Raman scattering (SERRS). Careful DPN-directed placement [...]

Scanning probe-based fabrication of 3D nanostructures via affinity templates, functional RNA and meniscus-mediated surface remodeling

Chung S., Presley A.D., Elhadj S., Hok S., Hah S.S., Chernov A.A., Francis M.B., Eaton B.E., Feldheim D.L., DeYoreo J.J., Lawrence Berkeley National Laboratory, US

Developing generic platforms to organize discrete molecular elements and nanostructures into deterministic patterns at surfaces is one of the central challenges in the field of nanotechnology. Here we review three applications of the atomic force [...]

Templated virus deposition: from molecular-scale force measurements to kinetic Monte Carlo simulations

Elhadj S., Gilmer G.H., Friddle R.W., Estrada M., Manchester M.E., Johnson J.E., De Yoreo J.J., Noy A., Lawrence Livermore National Laboratory, US

The use of macromolecular scaffolds for hierarchical organization of molecules and materials is a common strategy in living systems that leads to emergent behavior. One characteristic of this strategy is that it generates micron-scale structures [...]

Molecular dynamics study of ballistic rearrangement of surface atoms during high energy ion bombardment on Pd (001) surface

Kim S.-P., Lee K-R, Korea Institute of Science and Technology, KR

In this work, we employed MD simulation to investigate the details of the surface structure evolution during high energy Ar bombardment on Pd (001) surface. From the statistical manner by summing up for 1,000 independent [...]

Replication of micro/nano combined structure using micro/nano combined aluminum stamp

Cha K.J., Kwon T.H., POSTECH, KR

This paper presents an easy and efficient fabrication method of plastic replicas of micro/nano combined structures using an aluminum stamp with micro/nano combined structures (ASMNCS) on its surface. ASMNCS could be fabricated by two steps: [...]

Synthesis and X-ray photoelectron spectroscopy studies of poly(vinyl pyrrolidone) capped gold nanoparticles in a hybrid composite

Mishra A., Tripathy P., Ram S., Fecht H-J., Indian Institute of Technology, IN

Gold nanoparticles are synthesized by direct reduction of an aqueous solution of the metal salt with a surface regulating polymer N-polyvinyl pyrrolidone (PVP), which bind on the gold surface, insulate the particles from Au3+ and [...]

Au Nanoparticle Coupled- Surface Plasmon Resonance Immuno-sensor for Sensitivity Enhancement

Kim H-S, Kim J.H., Kim H-S, Kim J.H., Ko S-H., Cho Y-J, Kim H-S, Kim J.H., Ajou University, KR

In order to overcome the sensitivity limitation of SPR, nanoparticle-coupled SPR biosensors have explored since nanoparticles may significantly enhance the sensitivity by 1-2 orders of magnitude. Although the nanoparticle conjugated method contributes to the enhancement [...]

Fluorination effects on tribological characteristics of hydrogenated amorphous carbon thin films

Rubio-Roy M., Portal S., Polo M.C., Pascual E., Bertran E., Andújar J.L., Universitat de Barcelona, ES

Hydrogenated amorphous carbon (a C:H) films are good candidates for biomedical applications, requiring smooth surfaces, biocompatibility and singular tribological characteristics. The addition of elements to a C:H films, such as oxygen, silicon, fluorine or metals, [...]

Oxygen plasma treated superhydrophobic nozzle for electrospray device

Lee S., Lee Y., Byun D., Tran S.B.Q., Kim S., Park B., Lee S., Lee Y., Konkuk University, KR

When the meniscus of liquid is subject to strong electric field, electric charge is induced on the meniscus and electrostatic force elongates the liquid to form a cone-jet. This electrospray phenomenon can be applied to [...]
