Dynamic study on Nanometer size square Permalloy (NiFe) antidot arrays; use as Monolithic Microwave localize band-pass filter

Kuanr B.K., Malkinski L.M., Yu M., Scherer D., Camley R., Celinski Z., University of Colorado at Colorado Springs, US

Arrays of magnetic antidots (holes) have attracted extensive attention these days due to their potential application for high density data storage. In this investigation we fabricated antidots by means of electron-beam lithography and lift-off techniques [...]

Fabrication and optical properties of nanoscale arrays of Au and Pd in polymers

Atre S.V., Bhowmik S., Valmikanathan O.P., Ostroverkhova O., Oregon Nanoscience & Microtechnologies Institute, US

We report the fabrication of regular repeat structures of Au and Pd square islands embedded in polymethyl methacrylate (PMMA) and polycarbonate (PC). Using focussed ion beam (FIB), square islands were machined over a 5 micron [...]

Synthesis of one-dimensional titanium dioxide nanostructures

Cottam B., Chyla S., Menzel R., Bismarck A., Shaffer M., Imperial College London, UK

Finely structured titanium dioxide is a technological material of long-standing importance for many applications including pigments and catalysis. There is growing interest in smaller, truly nano-sized titanium dioxide particles with well-defined crystallinity and a range [...]

Surface plasmon polariton assisted organic solar cells

Kim C., Kim J., Lee J-Y, Peumans P., Kim C., Kim J., Duke University, US

A fundamental limitation of organic photovoltaic (OPV) cells is due to the trade-off between light absorption and exciton diffusion. We show that light absorption in an OPV cell can be enhanced by replacing a conventional [...]

Low Cost Fabrication of Micro- and Nanopores in Free-Standing Polymer Membranes for Study of Lipid Adsorption

Choi J., Roychowdhury A., Park S., Louisiana State University, US

We will show a technology utilizing all parallel processes to produce free-standing polymer membranes with perforated pores down to ~ 100 nm diameter and use of the membrane structure to study adsorption of a lipid, [...]

A Brief History of Thiols: An assembly of self-assembly

Graham D.J., Asemblon Inc., US

Highlights the history and development of Thiols and SAMs

Nanolithographic Patterning of Catalysts for Synthesis of Carbon Nanotubes

Gargate R.V., Banerjee D., Texas A&M University, US

Carbon nanotubes (CNT) were synthesized on specially custom designed MEMS chips under ambient conditions without requiring conventional Chemical vapor deposition(CVD) apparatus or process gases. In this approach, a layer of fullerene (C60) of 200 nm [...]

Commercially Available High-Throughput Dip Pen Nanolithography®

Haaheim J., Nafday O., Fragala J., Shile R., Val V., NanoInk, US

We present methods and applications of the commercially available 2D nano PrintArray(TM), which provides massive scalability for dip pen nanolithography. We will discuss current applications and future development.

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 [...]
