Tip-enhanced Raman scattering (TERS) of oxidised glutathione on an ultraflat gold nanoplate

Tip-enhanced Raman scattering (TERS) spectra of a short immobilised peptide on a single transparent gold nanoplate are presented.

Optical Properties of Individual Silicon Nanowires for Photonic Devices

Silicon is a high refractive index material. Consequently, silicon nanowires (SiNWs) with diameters on the order of the wavelengths of visible light show strong resonant field enhancement of the incident...

Volume Fraction Determination of Binary Liquid Mixtures by Measurement of the Equalization Wavelength

Kinetic Studies of Surface-Initiated Atom Transfer Radical Polymerization in the Synthesis of Magnetic Fluids

We present results from kinetic studies on the surface-initiated atom transfer radical polymerization in the preparation of polymer brush-coated magnetic particles from a heterogeneous system. It is shown...

Excited-State Planarization as Free Barrierless Motion in a pi-Conjugated Terpyridine

We present femtosecond time-resolved transient absorption data and results from nanosecond time-resolved emission studies for an extended terpyridine system (4′-(4-((2,5-bis(octyloxy)-4-styrylphenyl)ethynyl)phenyl)-2,2′:6′,2′′-terpyridine)....

Nonlinear absorption in single LaF3 and MgF2 layers at 193 nm measured by surface sensitive laser induced deflection technique

We report nonlinear absorption data of LaF3 and MgF2 single layers at 193 nm. A highly surface sensitive measurement strategy of the laser induced deflection technique is introduced and applied to measure...

Spectrally resolved cavity ring down measurement of high reflectivity mirrors using a supercontinuum laser source

We investigate a cavity ring down setup that offers the possibility to measure the spectrally resolved reflectivities of high reflectivity mirrors. The setup consists of a resonator (ring down cavity)...

Probing Liquid-Liquid Interfaces with Spatially Resolved NMR Spectroscopy

En route to nanometer resolution: Spatially resolved NMR spectroscopy is used to directly probe liquid–liquid interfaces with exceptionally high spatial resolution in one selected dimension. The novel...

Transparent Silver Microcrystals: Synthesis and Application for Nanoscale Analysis

Micrometer-sized atomically flat silver nanoplates with a thickness of 10-20 nm were obtained in a one-pot reduction of silver nitrate with hydrazine sulfate without surfactants or polymers. The optically...

Flexible Biochips for Detection of Biomolecules

Miniaturization of biosensors is envisaged by the development of biochips consisting of parallel microarray patterns of binding sites on rigid substrates, such as glass or silicon. Thin plastic substrates...
