Comparison of multiscale imaging methods for brain research
A major challenge in neuroscience is how to study structural alterations in the brain. Even small changes in synaptic composition could have severe outcomes for body functions. Many neuropathological diseases...
PublikationenFluorescence Microscopy of the HIV-1 Envelope
Human immunodeficiency virus (HIV) infection constitutes a major health and social issue worldwide. HIV infects cells by fusing its envelope with the target cell plasma membrane. This process is mediated...
PublikationenTheory of four-wave mixing for bound and leaky modes
We present a comprehensive theory of four-wave mixing in waveguide geometries, providing a rigorous description of the dynamics of both bound as well as leaky modes within a single theoretical framework....
PublikationenBi-metallic Pd/Au Nanoparticles prepared by UV-Excimer Laser exposure
Multi-metallic nanoparticles are useful for applications in biophotonics or catalysis. Metal compounds alter the properties of pure metallic nanoparticles and thus expand the particle performance compared...
PublikationenMolecular investigations on a chimeric strain of Staphylococcus aureus sequence type 80
A PVL-positive, methicillin-susceptible Staphylococcus aureus was cultured from pus from cervical lymphadenitis of a patient of East-African origin. Microarray hybridisation assigned the isolate to clonal...
PublikationenMicrofluidic Chamber Design for Controlled Droplet Expansion and Coalescence
The defined formation and expansion of droplets are essential operations for droplet-based screening assays. The volumetric expansion of droplets causes a dilution of the ingredients. Dilution is required...
Publikationen2 MW peak power generation in fluorine co-doped Yb fiber prepared by powder-sinter technology
We report on the first implementation of a fluorine co-doped large-mode-area REPUSIL fiber for high peak power amplification in an ultrashort-pulse master oscillator power amplifier. The core material...
PublikationenBeyond Beer’s law: Revisiting the Lorentz-Lorenz equation
In this contribution we show how the Lorentz-Lorenz and the Clausius-Mosotti equations are related to Beer’s law. Accordingly, the linear concentration dependence of absorbance is a consequence of neglecting...
PublikationenMolecular investigations on a chimeric strain of Staphylococcus aureus sequence type 80
An Eritrean patient was admitted with suspected tuberculous cervical lymphadenitis. While no mycobacteria were detected in pus from this process, culture yielded PVL-positive, methicillin-susceptible Staphylococcus...
Publikationen2-LED-Spectrophotometer for Rapid On-Site Detection of Pathogens Using Noble-Metal Nanoparticle-Based Colorimetric Assays
Novel point-of-care compatible methods such as colorimetric assays have become increasingly important in the field of early pathogen detection. A simple and hand-held prototype device for carrying out...
