2014-03-22 · Surface plasmon resonance-induced photoactivation of gold nanoparticles as bactericidal agents against methicillin-resistant Staphylococcus aureus. Mocan L (1), Ilie I (2), Matea C (1), Tabaran F (1), Kalman E (1), Iancu C (1), Mocan T (3). 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.

In this study, we investigated use of local surface plasmon resonance (LSPR) of metal nanoparticles (NPs) as a correlative light and electron microsco. Surface plasmon resonance (SPR) was observed when a planar close-packed assembly of gold nanoparticles (Au NPs) is adsorbed at the water|1,2-dichloroethane interface.

The unique shape-dependent plasmon resonance of gold nanoparticles which covers a wide range of the visible spectrum, was reported. Nanoparticle extinction has both light absorption and scattering components which are size- and shape-dependent, and may have the same wavelength dependence.

For small (~30nm) monodisperse gold nanoparticles, the surface plasmon resonance phenomenon causes an absorption of light in the blue-green portion of the spectrum (~450 nm) while red light (~700 nm) is reflected, yielding a rich red color. We show that the spectral response of this system results from the interplay between the localized plasmon resonance of the nanoparticle and the surface plasmon polaritons of the gold film, as previously predicted by theoretical studies. As a result of aggregation, the localized surface plasmon resonance band of gold nanoparticles decreased to around 525 nm and a new red-shifted band at 640 nm appeared which increases gradually as the function of Cefixime concentration. A unique detection limit (2.5 ng mL-1) was achieved for Cefixime in comparison with other colorimetric methods.
