Fluorescence Upconversion by Triplet-Triplet Annihilation in all-organic Poly(methacrylate)-Terpolymers
Fluorescence upconversion by triplet-triplet annihilation is demonstrated for a fully polymer-integrated material, i.e. in the limit of restricted diffusion. Organic sensitizer and acceptor are covalently...
PublikationenUnraveling the Light-Activated Reaction Mechanism in a Catalytically Competent Key Intermediate of a Multifunctional Molecular Catalyst for Artificial Photosynthesis
Understanding photodriven multielectron reaction pathways requires the identification and spectroscopic characterization of intermediates and their excited-state dynamics, which is very challenging due...
PublikationenNanoscale dynamics of cholesterol in the cell membrane
Cholesterol constitutes _30–40% of the mammalian plasma membrane, a larger fraction than of any other single component. It is a major player in numerous signaling processes as well as in shaping molecular...
PublikationenThe role of Ezrin in hepatocytes in the onset of excretory liver failure
Introduction: Ezrin and Radixin belong to the ERM protein family and share a high sequence homology. ERM proteins couple the cytoskeleton to integral plasma membrane proteins and thereby contribute to...
PublikationenRapid culture-based identification of Shiga toxin-producing Escherichia coli and Shigella spp./Enteroinvasive E. coli using the eazyplex® EHEC complete assay
Shiga toxin–producing Escherichia coli (STEC) and Shigella spp./enteroinvasive E. coli (EIEC) are common diarrheagenic bacteria that cause sporadic diseases and outbreaks. Clinical manifestations vary...
PublikationenElectroforming-free resistive switching in yttrium manganite thin films by cationic substitution
We report unipolar resistive switching in polycrystalline, hexagonal yttrium manganite thin films grown on unpatterned Pt metal coated SiO2/Si substrates with circular Al top electrodes. Electroforming-free...
PublikationenMultimodal Nonlinear Microscopy for Therapy Monitoring of Cold Atmospheric Plasma Treatment
Here we report on a non-linear spectroscopic method for visualization of cold atmospheric plasma (CAP)-induced changes in tissue for reaching a new quality level of CAP application in medicine via online...
PublikationenHigh-content screening Raman spectroscopy (HCS-RS) of panitumumab-exposed colorectal cancer cells
Raman spectroscopy can provide the biomolecular fingerprint of a cell in a label-free manner. Although a variety of clinical and biomedical applications have been demonstrated, the method remains largely...
PublikationenFiber-array-based Raman hyperspectral imaging for simultaneous chemical selective monitoring of particle size and shape of active ingredients in analgesic tablets
The particle shape, size and distribution of active pharmaceutical ingredients (API) are relevant quality indicators of pharmaceutical tablets due to their high impact on the manufacturing process. Furthermore,...
PublikationenLabel-free CARS microscopy through a multimode fibre endoscope
Multimode fibres have recently been employed as high-resolution ultra-thin endoscopes, capable of imaging biological structures deep inside tissue in vivo. Here, we extend this technique to label-free...
