Metal-Mediated Reaction Modeled on Nature: The Activation of Isothiocyanates Initiated by Zinc Thiolate Complexes
On the basis of detailed theoretical studies of the mode of action of carbonic anhydrase (CA) and models resembling only its reactive core, a complete computational pathway analysis of the reaction between...
PublicationsDetection of thiopurine methyltransferase activity in lysed red blood cells by means of lab-on-a-chip surface enhanced Raman spectroscopy (LOC-SERS)
In this contribution, the great potential of surface enhanced Raman spectroscopy (SERS) in a lab-on-a-chip (LOC) device for the detection of analyte molecules in a complex environment is demonstrated....
PublicationsLaterally Resolved and Direct Spectroscopic Evidence of Nanometer-Sized Lipid and Protein Domains on a Single Cell
Tip-enhanced Raman spectroscopy is used as a label-free, nondestructive method for the direct mapping of nanometer-sized lipid and protein domains on the surface of a single cell (see graphic). Spectral...
PublicationsSimplified formulas for non-normal reflection from monoclinic crystals
Based on Berreman's 4×4 matrix formalism [W. Berreman, J. Opt. Soc. Am. 62, 502 (1972)] we derive simplified expressions for the reflection formulas from the a–c crystal surface for non-normal incidence....
PublicationsDetection of PCR products amplified from DNA of epizootic pathogens using magnetic nanoparticles and SERS
Here we present a novel approach using surface-enhanced Raman scattering (SERS) spectroscopy for the sequence-specific detection of DNA utilizing magnetic nanoparticles (MNPs) for the enrichment of the...
PublicationsHydrogen bonding in different pyrimidine-methanol clusters probed by polarized Raman spectroscopy and DFT calculations
We report on the hydrogen bonding between pyrimidine (Pd) and methanol (M) as H-donor in this study. Hydrogen bonds between pyrimidine andmethanolmolecules as well as those between differentmethanolmolecules...
PublicationsOptical resonances of self-organized monocrystalline Au nanoparticles embedded in SrTiO3 matrix
We report on a novel fabrication scheme obtaining metal nanoparticles grown in a crystal high index ambient, i.e. SrTiO3 (STO). Starting from a deposited Au layer ellipsoidal and orientated Au nanoantennas...
PublicationsSpectral optical monitoring of nitrate in inland and seawater with miniaturized optical components
Miniaturized spectral analytical systems become ever increasingly important for in situ monitoring of natural waters’ nutrients, such as nitrate, phosphate or ammonium. A miniaturized UV spectral photometer...
PublicationsMicrostructured Optical Fiber Sensors Embedded in a Laminate Composite for Smart Material Applications
Fiber Bragg gratings written in highly birefringent microstructured optical fiber with a dedicated design are embedded in a composite fiber-reinforced polymer. The Bragg peak wavelength shifts are measured...
PublicationsMikrospektroskopie an lebenden Pilzen und Pflanzen
Um Wachstumsvorgänge in Pilzen oder Umwelteinflüsse auf Pflanzen zu untersuchen, eignen sich Verfahren der Ramanspektroskopie und -mikroskopie. Sie machen in lebenden Organismen die Morphochemie sichtbar,...
