Label-free monitoring of plasmonic catalysis on the nanoscale

Plasmonics is describing specific light mater interactions of metallic structures. In general the size of such structures is well in the nanometer regime and also determines specific behaviors like color,...

Fiber probe for nonlinear imaging applications

Over the past years it had been demonstrated that multimodal imaging combining the nonlinear modalities coherent anti-Stokes Raman scattering (CARS), two-photon excited auto-fluorescence (TPEF) and second...

Dielectrophoresis based integration of nanostructures and their sensorial application

Microbial respiration and natural attenuation of benzene contaminated soils investigated by cavity enhanced Raman multi-gas spectroscopy

Soil and groundwater contamination with benzene can cause serious environmental damage. However, many soil microorganisms are capable to adapt and are known to strongly control the fate of organic contamination....

Detailed numerical investigation of the interaction of longitudinal acoustic waves with fiber Bragg gratings in suspended-core fibers

The interaction between longitudinal acoustic waves and fiber Bragg gratings in suspended-core optical fibers is numerically investigated. The fiber core size and the air hole size are varied, and the...

Benchmark datasets for 3D MALDI- and DESI-imaging mass spectrometry

Three-dimensional (3D) imaging mass spectrometry (MS) is an analytical chemistry technique for the 3D molecular analysis of a tissue specimen, entire organ, or microbial colonies on an agar plate. 3D-imaging...

Exploring the Nanoscale: Fifteen Years of Tip-Enhanced Raman Spectroscopy

Spectroscopic methods with high spatial resolution are essential to understand the physical and chemical properties of nanoscale materials including biological and chemical materials. Tip-enhanced Raman...

Non-linear imaging and characterization of atherosclerotic arterial tissue using combined SHG and FLIM microscopy

Atherosclerosis is one of the leading causes of death in the Western World and its characterization is extremely interesting from the diagnostic point of view. Here, we employed combined SHG-FLIM microscopy...

Multiscale spectroscopy using a monolithic liquid core waveguide with laterally attached fiber ports

In conventional absorption spectrometers, the range of accessible concentrations of analytes in aqueous solution is significantly limited by the dynamic range of the measurement system. Here we introduce...

ZrO2 nanoparticles labeled via a native protein corona: detection by fluorescence microscopy and Raman microspectroscopy in rat lungs

ZrO2 nanoparticles are frequently used in composite materials such as dental fillers from where they may be released and inhaled upon polishing and grinding. Since the overall distribution of ZrO2 NP inside...
