Magnetic fluid hyperthermia: focus on superparamagnetic iron oxide nanoparticles
Due to their unique magnetic properties, excellent biocompatibility as well as multi-purpose biomedical potential (e.g., applications in cancer therapy and general drug delivery), superparamagnetic iron...
PublikationenCrisp and soft multivariate methods visualize individual cell nuclei in Raman images of liver tissue sections
Raman and infrared spectroscopy have been recognized to be promising tools in clinical diagnostics because they provide molecular contrast without external stains. Here, vertex component analysis (VCA)...
PublikationenCrystallization of alpha- and beta-carotene in the foregut of Spodoptera larvae feeding on a toxic food plant
In the animal kingdom, carotenoids are usually absorbed from dietary sources and transported to target tissues. Despite their general importance, the uptake mechanism is still poorly understood. Here we...
PublikationenHigh force measurement sensitivity with fiber Bragg gratings fabricated in uniform-waist fiber tapers
Fiber Bragg gratings (FBGs) inscribed in the waist of tapered photosensitive fibers offer specific attractive properties for sensing applications. A small-diameter fiber reduces structural influences for...
PublikationenOptimized coherence parameters for high-resolution holographic microscopy
A holographic in-line microscope setup with a glass sample carrier commonly uses a coherent laser light source, with the disadvantage of an incomplete suppression of disturbing interferences and coherence...
PublikationenCombination of Patch Clamp and Raman Spectroscopy for Single-Cell Analysis
In this contribution we present the combination of patch clamp with Raman spectroscopy for a label-free quantitative detection of intracellular components. Patch clamp is used to gain controlled access...
PublikationenExcited-State Dynamics of Protochlorophyllide Revealed by Subpicosecond Infrared Spectroscopy
To gain a better understanding of the light-induced reduction of protochlorophyllide (PChlide) to chlorophyllide as a key regulatory step in chlorophyll synthesis, we performed transient infrared absorption...
PublikationenTowards a fast, high specific and reliable discrimination of bacteria on strain level by means of SERS in a microfluidic device
The interest in a fast, high specific and reliable detection method for bacteria dentification is increasing. We will show that the application of vibrational spectroscopy is feasible for the validation...
PublikationenThe molecular mechanism of dual emission in terpyridine transition metal complexes—ultrafast investigations of photoinduced dynamics
Temperature dependent luminescence experiments are combined with femtosecond time-resolved transient absorption spectroscopy to decipher the photoinduced excited-state relaxation pathway in mononuclear...
PublikationenPhotoluminescence and Raman Scattering in Wet Chemically Etched Silicon Nanowires
Silicon nanowires with mean diameters of about 50-100 nm formed by wet-chemical etching of crystalline silicon wafers with low and high doping level were investigated by means of photoluminescence and...
