Guided-mode resonance absorption in partly oxidized thin silver films

The complex Ni[S2C2(CF3)2]2 reacts with light olefins, including ethylene and propylene, selectively and reversibly. The reaction is not poisoned by hydrogen gas, carbon monoxide, acetylene, or hydrogen sulfide, which are commonly present in olefin streams, presumably because olefin binding occurs through the sulfur ligand rather than the metal center. The reversible reaction of olefins with Ni[S2C2(CN)2]2n (n = 0, -1, -2) can be controlled electrochemically, where the oxidation state-dependent binding and release of olefins are fast on the electrochemical time scale. The observed tolerance to poisons and controllable electrochemical reactivity present an alternative approach to the separation of olefins from complex streams.

“…While silver films with a narrower SPR curve in the visible band yield higher sensitivity, gold films are employed more frequently because gold is chemically stable and reliable compared with a silver film [13,14]. On the other hand, it has been known that a surface plasmon wave propagating along the silver surface is less attenuated and exhibits higher localization of electromagnetic field in the dielectric medium than SPPs supported by a FIG.…”

Plasmonic-based biosensing technologies have been successfully commercialized and applied for monitoring various biomolecular interactions occurring at a sensor surface. In particular, the recent advances in nanofabrication methods and nanoparticle syntheses provide a new route to overcome the limitations of a conventional surface plasmon resonance biosensor, such as detection limit, sensitivity, selectivity, and throughput. In this paper, optical and physical properties of plasmonic nanostructures and their contributions to a realization of enhanced optical detection platforms are reviewed. Following vast surveys of the exploitation of metallic nanostructures supporting localized field enhancement, we will propose an outlook for future directions associated with a development of new types of plasmonic sensing substrates.

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Since the dispersion property of SPR exists in the total reflection region, it had been studied with the attenuated total reflection (ATR) method. SPR is a specific absorption which is sensitive to the dielectric constant and thickness of the metallic material, resulting in strong absorption of light as a function of incident angle, wavelength and polarization of light.…”

We report the real-time visualization technique of surface plasmon resonance (SPR) with the spectroscopic attenuated total reflection (S-ATR). Using this technique, light absorption due to SPR on thin metal films by the white light were clearly visualized on a twodimensional detector such as CCD camera in the coordination of the incident angle and the wavelength. Metal films could be distinguished even in partially oxidized condition. The realtime SPR visualization would be useful for monitoring of biochemical reactions as well as for fabricating plasmonic devices.
