The structure and the stability of the transferred monolayers of gold-thiol nanoparticles, formed at air-water interface at different surface pressure, on to silicon surface have been studied using two complementary techniques, x-ray reflectivity and atomic force microscopy (AFM). Networklike nanopatterns, observed through AFM, of the in-plane aggregated nanoparticles can be attributed to the l...

Transparent conductive oxide (TCO) thin films are cornerstones in many optoelectronic applications including displays, photovoltaics and touchscreens. In these devices, with simultaneous high optical transparency electrical conductivity needed. Ideally, heat generated during normal device operation must ideally be compensated for to achieve optimum functionality. One possible way address the th...

We have studied nanometer-scale features observed with scanning tunneling microscopy on nitrogen (N)-adsorbed Cu(001) surfaces. Grid-like nanopattern aligned in [100] directions at a medium N-coverage and trenches along [110] appearing higher are frequently reported. In addition, we “diagonal lines” grid-patterned surface “dark curves” growing from the trench ends. All above responsible for rel...

Abstract Nanopatterned surfaces play a key role for many applications exploiting unique features such as an enhanced surface area, long- and short-ranged morphology modulations or spatial variation of electronic chemical properties. Ion beam irradiation has been frequently used nanostructuring bulk materials because it is efficient, fast, cost-effective. In this paper we show that ion under ext...

2D imaging of biochips is particularly interesting for multiplex biosensing. Resonant properties allow label-free detection using the change of refractive index at the chip surface. We demonstrate a new principle of Scanning Of Resonance on Chip by Imaging (SORCI) based on spatial profiles of nanopatterns of resonant waveguide gratings (RWGs) and its embodiment in a fluidic chip for real-time b...

Cells are known to be surrounded by nanoscale topography in their natural extracellular environment. The cell behavior, including morphology, proliferation, and motility of bovine pulmonary artery smooth muscle cells (SMC) were studied on poly(methyl methacrylate) (PMMA) and poly(dimethylsiloxane) (PDMS) surfaces comprising nanopatterned gratings with 350 nm linewidth, 700 nm pitch, and 350 nm ...

Extraordinary Optical Transmission Plasmonic Color Filters (EOT-PCFs) with nanostructures have the advantages of consistent color, small size, and excellent color reproduction, making them a suitable replacement for colorant-based filters. Currently, gamut created by plasmonic filters is limited to standard red, green, blue (sRGB) space, which limits their use in future. To address this limitat...
