Novel Bottom-Up SERS Substrates for Quantitative and Parallelized Analytics

Fiber Bragg grating based spatially resolved characterization of flux-pinning-induced strain of disk-shaped bulk YBCO samples

A new optical method for the characterization of magnetostrictive effects in bulk superconductors will be presented. Several of wavelength encoded fiber Bragg gratings can be inscribed in one fiber with...

Lithographically patterned silicon nanowire arrays for matrix free LDI-TOF/MS analysis of lipids

Silicon nanowire arrays were patterned onto silicon chips by a combination of lithography and chemical vapor deposition using the vapor-liquid-solid growth method. Thus, highly reproducible sample deposition...

A comparative Raman and CARS imaging study of colon tissue

An experimental evaluation of the information content of two complimentary techniques, linear Raman and coherent anti-Stokes Raman scattering (CARS) microscopy, is presented. CARS is a nonlinear variant...

Relationship between molecular structure and Raman spectra of quinolines

DFT calculations were applied to investigate the relationship between the molecular structure and the Raman spectra of quinolines. A variety of different quinolines with increasing complexity was investigated...

Direct fabrication of surface relief gratings in chalcogenide glasses by excimer laser interference lithography

In this paper we study the possibility to realise surface relief gratings in thin chalcogenide glass films by holographic exposure using a pulsed KrF excimer laser. Gratings with a period of 540 nm and...

Second harmonic generation as a technique to probe buried interfaces

Since the advances of femtosecond laser technology during the last decade, optical second harmonic generation (SHG) has proven itself a powerful tool to investigate the electronic and structural properties...

Fast measurement of fluorine distribution in doped fused silica by pulsed Raman scattering

We present short time measurements to determine the distribution of fluorine dopant in extended fused silica samples. These measurements are based on pulsed Raman spectroscopy. Our investigations are starting...

Nanoimaging for prion related diseases

Misfolding and aggregation of prion proteins is linked to a number of neurodegenerative disorders such as Creutzfeldt- Jacob disease (CJD) and its variants: Kuru, Gerstmann-Straussler-Scheinker syndrome...

Raman to the limit: tip-enhanced Raman spectroscopic investigations of a single tobacco mosaic virus

The development of fast identification techniques of viruses is an ongoing important research topic. Conventional virus detection and identification is generally based on various different microbiological...
