“…Gold Nps have been intensively studied in the past decade due to their potential in different applications [8,9] such as chemical catalysis, [10] optoelectronic devices, pathogenic bacteria, [11] chemical and bio-sensors, [10,12] catalysts for the growth of aligned one-dimensional (1D) nanostructures [13,14] and biofuel cells. [15] One interesting property of AuNPs is their aggregations when salt is introduced.…”

We have explored the potential of using gold nanoparticles (Au-NPs) in optical and bare-eye discrimination of (a) proteins (such as bovine serum albumin and lysozyme), (b) homo-polynucleotides (such as poly-adenylic acid, polycytidylic acid, poly-uridylic acid and poly-inosinic acid), and (c) long chain DNA (from salmon, herring and thym). Such biomacromolecules can be detected and discriminated due to their ability to prevent the formation of blue aggregates from red (non-aggregated) citrate capped Au-NPs on addition of NaCl. The effect of these biomacromolecules on the aggregation was investigated by colorimetry and UV-vis spectrometry. The results show that the two proteins can be differentiated by colorimetry, and also salmon ssDNA and dsDNA. The AuNPs can also discriminate the dsDNAs of salmon and herring. We conclude that the use of Au-NPs represent a viable candidate to future methods of DNA analysis on the basis of visual testing, particularly in the area of food analysis.

“…In recent years, various techniques, based on "nanosphere lithography", have been reported for nano/microfabrication or nano/micropatterning of a wide variety of solid substrates including metals, [44][45][46][47][48] semiconductors 49,50 and ceramics. 51 Recently, we reported structuring surface by nanospheres lithography and measured the adhesion force.…”

The adhesion between a micro/nano-object and a micro-gripper end-effector is an important problem in micromanipulation. Cancelling or reduction this force is a great challenge.This force is directly linked to the surface chemical structure of the object and the gripper. We propose to predict this force between a structuring surface and a micro-object with a multisphere van der Waals force model. The surface was structured by polystyrene latex particles (PS particles) with radii from 35 to 2000 nm. The model was compared with experimental pulloff force measurement performed by AFM with different natures of spheres materials glued on the tipless. A wide range of applications, in the field of telecommunications, bioengineering, and more generaly speaking MEMS can be envisaged for these substrates. † FEMTO-ST Institute ‡ IEMM ¶ EMPA

“…However, given the same growth conditions, growth dynamics of nanowires depends in a high degree on their dimensions and center-to-center distance [25][26][27][28][29]. The nanoscale features for nanowire growth can be defined on a substrate by electron beam, nanosphere, phase-shift or nano-imprint lithography [30][31][32][33][34].…”

Semiconductor nanowire arrays are reproducible and rational platforms for the realization of high performing designs of light emitting diodes and photovoltaic devices. In this paper we present an overview of the growth challenges of III-V nanowire arrays obtained by molecular beam epitaxy and the design of III-V nanowire arrays on silicon for solar cells. While InAs tends to grow in a relatively straightforward manner on patterned (111)Si substrates, GaAs nanowires remain more challenging; success depends on the cleaning steps, annealing procedure, pattern design and mask thickness. Nanowire arrays might also be used for next generation solar cells. We discuss the photonic effects derived from the vertical configuration of nanowires standing on a substrate and how these are beneficial for photovoltaics. Finally, due to the special interaction of light with standing nanowires we also show that the Raman scattering properties of standing nanowires are modified. This result is important for fundamental studies on the structural and functional properties of nanowires.
