The dewetting of Au/Ag bi-layers on the periodically pre-patterned substrates leads to the formation of an array of Au-Ag alloy na-noparticles. The array of alloy nanoparticles is transformed into an array of nanoporous gold nanoparticles by a following dealloying step.

Gold nanoparticles show easily tuned physical properties, including unique optical properties, robustness, and high surface areas, making them ideal candidates for developing biomarker platforms.

Modulation of these physicochemical properties can be easily achieved by adequate synthetic strategies and give gold nanoparticles advantages over.

A thermoresponsive large-area plasmonic architecture, made from randomly distributed gold nanoparticles (GNPs) located at the substrate interface of a cholesteric liquid crystal (CLC) cell, is fabricated and thoroughly characterized.

The diverse structures and properties of nanoparticles make them useful tools for both fundamental studies and pragmatic applications in a range of disciplines.

This volume is intended to explore this diversity. The first section covers on formation of nanoparticles, and assembly of these systems into structured systems.

The second section focuses on both the fundamental physical properties of 5/5(1). Increasing interest has been devoted to preparing gold nanoparticle (GNP) functionalized TiO2 nanotube array (TNTA) nanocomposites (GNP/TNTA) for photocatalytic applications.

Nonetheless, achieving accurate control of surface assemblies of GNPs tethered on the TNTA substrate is far from satisfactory. Thus, i. Self-assembled monolayer of 10 nm gold nanoparticles. Monodispersed in size chemically synthesized gold nanoparticles covered with organic thiol-based shell (typically, C 8 H 17 SH, C 12 H 25 SH), being transferred on suspended water surface, form self-assembled monolayer (Nanoparticle Array), which can be then transferred on the Si substrate by soft lithography using PDMS stamps.

Surface Plasmon Resonance (SPR) When gold nanoparticles are exposed to a specific wavelength of light, the oscillating electromagnetic field of the light induces a collective coherent oscillation of the free electrons, which causes a charge separation with respect to the ionic lattice, forming a dipole oscillation along the direction of the electric field of the light.

A compact disk/digital versatile disk (CD/DVD) based immunoassay is a method for determining the concentration of a compound in research and diagnostic laboratories by performing the test on an adapted CD/DVD surface using an adapted optical disc drive; these methods have been discussed and prototyped in research labs since We report a simple and novel colorimetric sensor array for rapid identification of microorganisms.
