Dual-SNOM investigations of multimode interference in plasmonic strip waveguides

The ability of squeezing and guiding light in nanoscale plasmonic waveguides makes them especially interesting for photonic circuits. In spite of reported realizations of plasmonic waveguides, experimental...

Concentration of energy inside laser-irradiated gold and silver plasmon nanoparticles in air

We simulated laser-intensity distribution inside spherical gold and silver nanoparticles with radii between 10 and 100 nm, which are exposed to laser radiation at 400, 532, and 800 nm in air, and analyzed...

Localized surface plasmon resonance (LSPR) based biosensing

INTRODUCTION: Bioanalytical sensing based on the principle of localized surface plasmon resonance experiences is currently an extremely rapid development. Novel sensors with new kinds of plasmonic transducers...

The electric field standing wave effect in infrared transmission spectroscopy

When in IR absorbance spectra of films, which were converted from transmission, bands ratios are compared, then it can be noted that even after background correction and removal of interference fringes...

Metal-polymer Hybrid Nanoparticles for Correlative High-Resolution Light and Electron Microscopy

The combination of fluorescence microscopy and electron microscopy prom-ises a deeper insight into the ultrastructural features of cell organelles, e.g., after drug administration. Both methods complement...

Design and characterization of a plasmonic Doppler grating for azimuthal angle-resolved surface plasmon resonances

We present two-dimensional plasmonic Doppler grating (PDG) for broadband azimuthal angle-resolved nanophotonic applications. The PDG consists of a set of non-concentric circular rings mimicking the wavefronts...

Optical coherence tomography with nanoscale resolution using a laser-driven high-harmonic source

The use of extreme ultraviolet (XUV) radiation for nanoscale imaging has dis-tinctive advantages: It is label-free, facilitates high contrast, allows material identification and penetrates opaque matter....

Cargo-carrier-interactions significantly contribute to micellar conformation and biodistribution

Strategies to deliver drugs using nanocarriers, which are passively or actively targeted to their alleged site of action might favorably affect benefit-risk-profiles of novel therapeutics. Here, we tested...

A double self-assembly process for versatile reduced-graphene-oxide layer deposition and conformal coating on 3D structures

In this work we demonstrate a double self-assembly (DSA) process based on the surface interaction between graphene flakes (GFs) and surfactant molecules at water/air interface, leading to the formation...
