ESBL colonization and acquisition in a hospital population: The molecular epidemiology and transmission of resistance genes
A prospective cohort study (German Clinical Trial Registry, No. 00005273) was performed to determine pre-admission colonization rates, hospital acquisition risk factors, subsequent infection rates and...
PublicationsResonance Raman Spectro-Electrochemistry to Illuminate Photo-Induced Molecular Reaction Pathways
Electron transfer reactions play a key role for artificial solar energy conversion, however, the underlying reaction mechanisms and the interplay with the molecular structure are still poorly understood...
PublicationsRaman spectroscopy reveals LPS-induced changes of biomolecular composition in monocytic THP-1 cells in a label-free manner
The human innate immune system is able to recognize pathogen-associated molecular patterns like lipopolysaccharides (LPS) leading to the activation of signal cascades and the release of different cytokines....
PublicationsRaman spectroscopy follows time-dependent changes in T lymphocytes isolated from spleen of endotoxemic mice
T lymphocytes (T cells) are highly specialized members of the adaptive immune system and hold the key to the understanding the hosts’ response toward invading pathogen or pathogen-associated molecular...
PublicationsBiomedical imaging by means of linear and non-linear Raman microspectroscopy
Biomedical imaging by means of nonlinear Raman microspectroscopy offers novel approaches towards individualized decisions on therapy routines as diagnosis is possible on the chemical composition of tissue...
PublicationsScalable, High Power Line Focus Diode Laser for Crystallizing of Silicon Thin Films
We present the design and performance of a diode laser module producing a high intensity line focus at 808 nm for material processing. The design is based on a linear array of 7 laser bars and beam forming...
PublicationsFTIR, Raman, and CARS microscopic imaging for histopathologic assessment of brain tumors
The contribution demonstrates how the molecular contrast of Fourier transform infrared (FTIR), Raman and coherent anti-Stokes Raman scattering (CARS) microscopic imaging can be applied for the histopathological...
PublicationsMultimode Fabry-Perot Interferometer Probe based on Vernier Effect for Enhanced Temperature Sensing
New miniaturized sensors for biological and medical applications must be adapted to the measuring environments and should provide large measurement resolution to sense small changes. The Vernier effect...
PublicationsMagnetooptical response of permalloy multilayer structures on different substrate in the IR-VIS-UV spectral range
The magnetooptical (MO) response of Ru/Py/Ta thin film stacks with 4, 8, and 17 nm thick Ni81Fe19 permalloy (Py) films on a SiO2/Si and a ZnO substrate was measured by vector magnetooptical generalized...
PublicationsHolographic optical tweezers at the tip of a needle
Fibre-based optical tweezers typically rely on engineered fibre terminations yielding limited flexibility in number and positioning of trap sites. Here, we demonstrate holographic optical tweezers delivered...
