Chirped Phase Mask Interferometer for Fiber Bragg Grating Array Inscription

We present a phase mask inscription technique with two beam interferometry using a lateral non-homogeneous beam splitter to create gratings with non-homogeneous periods, so-called chirped fiber Bragg gratings....

Towards SERS based applications in food analytics: Lipophilic sensor layers for the detection of Sudan III in food matrices

Food safety is an actual topic of great importance for our society which places high demands on analytical methods. Surface enhanced Raman spectroscopy (SERS) meets the requirements for a rapid, sensitive...

Detection of harmful substances by employing surface enhaced Raman spectroscopy (SERS)

Raman spectroscopic approach to monitor the in vitro cyclization of creatine → creatinine

The cyclisation of creatine → creatinine occurs naturally in body through an enzymatic pathway. It acts as a primary source of energy during muscular activity. Several experimental techniques have been...

Droplet based microfluidics combined with surface-enhanced Raman spectroscopy: towards monitoring of Levofloxacin

Magnetic apatite for structural insights on the plasma membrane

The iron oxide-hydroxyapatite (FeOxHA) nanoparticles reported here differ from those reported before by their advantage of homogeneity and simple preparation; moreover, the presence of carboxymethyldextran...

Application of R-mode analysis to Raman maps: a different way of looking at vibrational hyperspectral data

Hierarchical cluster analysis (HCA) is extensively used for the analysis of hyperspectral data. In this work, hyperspectral data sets obtained from Raman maps were analyzed using an alternative mode of...

Towards on-site testing of Phytophthora species

Rapid detection and accurate identification of plant pathogens in the field is an ongoing challenge. In this study, we report for the first time on the development of a helicasedependent isothermal amplification...

Faraday rotation and photoluminescence in heavily Tb31-doped GeO2-B2O3-Al2O3-Ga2O3 glasses for fiber-integrated magneto-optics

We report on the magneto-optical (MO) properties of heavily Tb31-doped GeO2-B2O3-Al2O3-Ga2O3 glasses towards fiber-integrated paramagnetic MO devices. For a Tb31 ion concentration of up to 9.7 3 1021 cm23,...

Quantitative assessment of the degree of lipid unsaturation in intact Mortierella by Raman microspectroscopy

Fungi of the genus Mortierella can accumulate large amounts of unusual lipids depending on species, strain, and growth conditions. Fast and easy determination of key parameters of lipid quality for these...
