Fast detection of Sepsis pathogens by means of Raman spectroscopy

Micro-Raman Spectroscopy: a novel method for identification of Sepsis pathogens

How to pre-process Raman spectra for reliable and stable models?

Raman spectroscopy in combination with chemometrics is gaining more and more importance for answering biological questions. This results from the fact that Raman spectroscopy is non-invasive, marker-free...

Raman spectroscopic detection of physiology changes in plasmid-bearing Escherichia coli with and without antibiotic treatment

Bacterial resistances against antibiotics are increasingly problematic for medical treatment of pathogenic bacteria, e.g., in hospitals. Resistances are, among other genes, often encoded on plasmids which...

Precise Analysis of Small Wavenumber Shift of Pyridine on Dilution with H2O and D2O Using RDS Technique

The wavenumber difference (Δν) of the ring breathing mode (ν1), ring deformation mode (ν12) and C−H stretching mode (ν3) of pyridine (Py) dissolved in both H2O and D2 O at equal mole fractions of...

Broadband, diode-pumped Yb:SiO2 multicomponent glass laser

We successfully demonstrated cw lasing of Ytterbium-doped silica multicomponent glas bulk material. A slope efficiency of 43 % and a tuning range from 1010 - 1080 nm have been achieved.

Dispersion analysis of perpendicular modes in anisotropic crystals and layers

Until today dispersion analysis could not be successfully applied to evaluate oscillator parameters of modes that have their transition moments perpendicular to the surface of an anisotropic crystal or...

DNA hybridization assay at individual, biofunctionalized zinc oxide nanowires

Reliable and efficient identification of DNA is a major goal in on-site diagnostics. One dimensional nanostructures like nan-owires (NW) represent potential sensor structures due to their extreme surface-to-bulk...

Photocatalyst activation by intrinsic stimulation in TiO2-BaTiO3

Antibacterial surface coating is an efficient way to the incidence of microbial infections. Often a coating based on TiO2 is utilized because its photocatalysis has been demonstrated to be a competent...

Autofluorescence Imaging of Human RPE Cell Granules using Structured Illumination Microscopy

Background/aims To characterise single autofluorescent (AF) granules in human retinal pigment epithelium (RPE) cells using structured illumination microscopy (SIM). Methods Morphological characteristics...
