Richard g. Brereton: Chemometrics: data driven extraction for science, 2nd. ed.

Theoretical principles of Raman spectroscopy

This contribution reports on the theoretical foundations of Raman spectroscopy. Since the discovery of the Raman effect in 1928, Raman spectroscopy with its linear and nonlinear variants has established...

Liquid-Core Microstructured Polymer Optical Fiber as Fiber Enhanced Raman Spectroscopy Probe for Glucose Sensing

This work reports the development and application of two liquid-core microstructured polymer optical fibers (LCmPOF) with different microstructure sizes. They are used in a fiber-enhanced Raman spectroscopy...

Fiber Enhanced Raman Gas Spectroscopy for 18O-13C-labeling experiments

Stable isotopes are used in ecology to track and disentangle different processes and pathways. Especially for studies focused on the gas exchange of plants, sensing techniques that offer oxygen (O2) and...

Thermal illumination limits in 3D Raman microscopy: A comparison of different sample illumination strategies to obtain maximum imaging speed

Confocal Raman microscopy is a powerful tool for material science and biomedical research. However, the low Raman scattering cross-section limits the working speed, which reduces the applicability for...

Super-resolution microscopy demystified

Super-resolution microscopy (SRM) bypasses the diffraction limit, a physical barrier that restricts the optical resolution to roughly 250 nm and was previously thought to be impenetrable. SRM techniques...

Time-resolved study of site-specific corrosion in a single crystalline silver nanoparticle

We followed over 24 hours a corrosion process in monocrystalline triangular shaped nanoparticles at a single particle level by atomic force microscopy and optical spectroscopy techniques. We observed that...

Successful optimization of reconstruction parameters in structured illumination microscopy – A practical guide

The impact of the different reconstruction parameters in super-resolution structured illumination microscopy (SIM) on image artifacts is carefully analyzed. These parameters comprise the Wiener filter...

Simulation of the long-term fate of superparamagnetic iron oxide-based nanoparticles using simulated biological fluids

The long-term fate of superparamagnetic iron oxide nanoparticles (MNP) for biomedical applications represents a critical matter for human health. Investigations of the degradation behavior in in vivo tests...

Phenotypic antibiotic susceptibility testing of pathogenic bacteria using photonic read-out methods: Recent achievements and impact

The development of antibiotic resistances in common pathogens is an increasing challenge for therapy of infections and especially severe complications like sepsis. To prevent administration of broad-spectrum...
