Chip-based detection system for the on-site analysis of animal diseases

A portable and robust system which is suitable for the automated analysis of DNA or RNA of selected pathogens such as foot-and-mouth disease virus (FMDV) is developed. The system incorporates a stationary...

Correlating internal stresses, electrical activity and defect structure on the micrometer scale in EFG silicon ribbons

In the present paper, we study the influence of defects through their stress fields on the electrical activity and residual stress states of as-grownedge-definedfilm-feed(EFG)multicrystalline silicon (mc-Si)...

Thermally stable optical fibre Bragg grating wavelength reference

The inherent temperature dependence of optical fibre Bragg gratings is causedmainly by the positive thermo-optic effect of thefibre corematerial, and it results in an increase of Bragg wavelengthwith temperature....

Identification and classification of organic and inorganic components of particulate matter via Raman spectroscopy and chemometric approaches

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...

Detection 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....

Laterally 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...

Simplified 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....

Detection 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...
