Development of a highly balanced axial SQUID gradiometer

Applications of coherent Raman scattering microscopies to clinical and biological studies

Coherent anti-Stokes Raman scattering (CARS) microscopy and stimulated Raman scattering (SRS) microscopy are two nonlinear imaging modalities that are at the frontier of label-free and chemical specific...

Destruction-free procedure for the isolation of bacteria from sputum samples for Raman spectroscopic analysis

Abstract Lower respiratory tract infections are the fourth leading cause of death worldwide. Here, a timely identification of the causing pathogens is crucial to the success of the treatment. Raman spectroscopy...

MultiFocus Polarization Microscope (MF-PolScope) for 3D polarization imaging of up to 25 focal planes simultaneously

We have developed an imaging system for 3D time-lapse polarization microscopy of living biological samples. Polarization imaging reveals the position, alignment and orientation of submicroscopic features...

Characterization of carotenoids in soil bacteria and investigation of their photodegradation by UVA radiation via resonance Raman spectroscopy

A soil habitat consists of an enormous number of pigmented bacteria with the pigments mainly composed of diverse carotenoids. Most of the pigmented bacteria in the top layer of the soil are photoprotected...

Magnetic Nanoparticles Adapted for Specific Biomedical Applications

Magnetic nanoparticles are used in different biomedical applications, whereby each application requires specific particle properties. To fulfil these requirements, particle properties have to be optimized...

Seamless stitching of tile scan microscope images

For diagnostic purposes, optical imaging techniques need to obtain high-resolution images of extended biological specimens in reasonable time. The field of view of an objective lens, however, is often...

Surface corrugating direct laser writing of microstructures in ternary chalcogenide films using a continuous-wave super-bandgap laser

Direct laser writing using a tightly focused 442 nm continuous-wave laser was applied to corrugate the surface of ternary As-S-Se chalcogenide thin films with high spatial resolution. The topography of...

Mode Coupling in Few-Mode Fibers Induced by Mechanical Stress

We investigate mode coupling in few-mode fibers induced by homogeneously and periodically applied mechanical stress. To view the power transfer between individual modes a modal decomposition is performed...

Optical glass fiber tips for photonic micro-sensor systems

The application potential of sub-structured fiber tips in optical sensor technology and photonic microsystems is high. The miniaturization of sensor systems and the technical implementation using optical...
