We report on photo-current generation in freestanding monolayered gold nanoparticle membranes excited by using a laser. The absence of a substrate leads to a 50% increase of the photocurrent at plasmon resonance. This current is attributed to a combination ...

Magneto-optical plasmonic heterostructure with ultranarrow resonance for sensing applications

Giovanni Dietler, Pavel Kapralov

Currently, sensors invade into our everyday life to bring higher life standards, excellent medical diagnostic and efficient security. Plasmonic biosensors demonstrate an outstanding performance ranking themselves among best candidates for different applica ...

Dispersion and shape engineered plasmonic nanosensors

Peer Fischer, Hyeonho Jeong

Biosensors based on the localized surface plasmon resonance (LSPR) of individual metallic nanoparticles promise to deliver modular, low-cost sensing with high-detection thresholds. However, they continue to suffer from relatively low sensitivity and figure ...

The Sommerfeld Halfspace Problem Redux: Alternative Field Representations, Role of Zenneck and Surface Plasmon Waves

Juan Ramon Mosig, Krzysztof Michalski

The problem of a vertical Hertzian dipole radiating in the presence of a lossy conducting halfspace, first formally solved by Sommerfeld in 1909, is revisited. Using rigorous operator theory concepts and the characteristic Green function procedure, alterna ...

Surface Plasmon Resonance of Nanoparticles and Applications in Imaging

Pierre Robert Maurice Millien

In this paper we provide a mathematical framework for localized plasmon resonance of nanoparticles. Using layer potential techniques associated with the full Maxwell equations, we derive small-volume expansions for the electromagnetic fields, which are uni ...

First demonstration of plasmonic GaN quantum cascade detectors with enhanced efficiency at normal incidence

Nicolas Grandjean, Etienne François Olivier Giraud

We have designed, fabricated and measured the first plasmon-assisted normal incidence GaN/AlN quantum cascade detector (QCD) making use of the surface plasmon resonance of a two-dimensional nanohole Au array integrated on top of the detector absorption reg ...

LSPR Chip for Parallel, Rapid, and Sensitive Detection of Cancer Markers in Serum

Sebastian Maerkl, Jose Luis Garcia Cordero

Label-free biosensing based on metallic nano-particles supporting localized surface plasmon resonances (LSPR) has recently received growing interest (Anker, J. N., et al. Nat. Mater. 2008, 7, 442-453). Besides its competitive sensitivity (Yonzon, C. R., et ...

Amer Chemical Soc2014

Sensing using surface plasmon resonances is one of the most promising practical applications of plasmonic nanostructures and Fano resonances allow achieving a lower detection limit thanks to their narrow spectral features. However, a narrow spectral width ...

Optical properties of mesogen-coated gold nanoparticles

Toralf Scharf

In this work, the physical and optical properties of gold nanoparticles functionalized with laterally grafted nematic ligands were studied. In particular, the influence of the nanoparticle size on the mesomorphic behavior and optical properties of the comp ...
