Gold nanoparticles (Au NPs) with an average size of about 10 nm were deposited in situ into the TiO 2 bi-layer structure. The extended photoelectrochemical (PEC) water splitting activity in visible light was ascribed to the energetic hot electrons and holes that were generated in the Au NPs through the excitation and decay of surface plasmons. 2012-06-08 · Surface plasmon resonance of layer-by-layer gold nanoparticles induced photoelectric current in environmentally-friendly plasmon-sensitized solar cell Abstract. Layer-by-layer gold nanoparticles are used to generate photocurrent in an environmentally-friendly Introduction. Nobel nanoparticles Metallic nanoparticles dispersed in host materials have many potential applications due to their unique optical properties. These properties are determined not only by the size, shape and composition of the particles, but also by their environment.

Heavy Metal Ion Sensing By Surface Plasmon Resonance on Gold

•Investigation of nano-size objects like nanoparticles or nanotubes. Gold-nanoparticles can be used as a robust tool for bio-sensing based on localized surface plasmon resonance (LSPR). Both local refractive index change and In this paper,we are trying to optimize the detection level of heavy metal ions by surface plasmon resonance on gold nanoparticles using UV-VIS spectroscopy.

Effects of the flow type on the immobilization of horseradish

SPR is the basis of many standard tools for measuring adsorption of material onto planar metal (typically gold or silver) surfaces or onto the surface of metal nanoparticles. In this study, we investigated use of local surface plasmon resonance (LSPR) of metal nanoparticles (NPs) as a correlative light and electron microscopy (CLEM) tag for biological samples. Gold NPs in ultra-thin sections for TEM revealed that LSPR could be observed … Shape-dependent plasmon resonances of gold nanoparticles Colleen L. Nehl† and Jason H.
