Characterization of different substrates for Raman spectroscopic imaging of eukaryotic cells

For Raman spectroscopic analyses of the cells and other biological samples, the choice of the right substrate material is very im-portant to avoid loss of information in characteristic spectral features...

Thin-Film-Based Ultralow Noise SQUID Magnetometer

We report on the development of an ultralow noise thin-film based SQUID magnetometer. A niobium thin-film pickup coil is connected to the input coil of a SQUID current sensor. The low capacitance of the...

The combination of optical coherence tomography and Raman spectroscopy for tissue characterization

The visualization as well as characterization of diseased tissue are of vital diagnostic interest for an early diagnosis to increase patients’ survival rate. In this study we introduce an imaging device...

Biomineralization of Mn oxides by Mn(II)-oxidizing bacilli from a contaminated soil

Fast label-free detection of Legionella spp. in biofilms by applying immunomagnetic beads and Raman spectroscopy

Legionellae colonize biofilms, can form a biofilm by itself and multiply intracellularly within the protozoa commonly found in water distribution systems. Approximately half of the known species are pathogenic...

Self-defining tree-like classifiers for interpretation of Raman spectroscopic experiments

In this contribution, a technique is proposed to create a data-driven interpretation of a given chemometric analysis of a Raman dataset. In real-world applications, the chemometric analysis is fixed by...

Hyperspectral imaging of plasmon resonances in metallic nanoparticles

The spectroscopy of metal nanoparticles shows great potential for label-free sensing. In this article we present a hyper-spectral imaging system combined with a microfluidic system, which allows full spectroscopic...

Demonstration of carbon catabolite repression in naphthalene degrading soil bacteria via Raman spectroscopy based stable isotope probing

Carbon catabolite repression (CCR) is a regulatory phenomenon occurring in both lower organisms like bacteria andhigher organisms like yeast which allows them to preferentially utilize a specific carbon...

Tunable nanoporous silicon oxide templates by swift heavy ion tracks technology

Nanoporous silicon oxide templates formed by swift heavy ion tracks technology have been investigated. The influence of the heavy ion characteristics, such as type of ion, energy, stopping power and irradiation...

Spatial Resolution of Tip-Enhanced Raman Spectroscopy – DFT Assessment of the Chemical Effect

Experimental evidence of extremely high spatial resolution of tip-enhanced Raman scattering (TERS) has been recently demonstrated. Here, we present a full quantum chemical description (at the density functional...
