Simultaneous Infrared Spectroscopy, Raman Spectroscopy, and Luminescence Sensing: A Multispectroscopic Analytical Platform
Scientific questions in fields such as catalysis, monitoring of biological processes, or environmental chemistry demand analytical technologies combining orthogonal spectroscopies. Combined spectroscopic...
Publications | 07.03.2023Diiodo-BODIPY sensitizing of [Mo3S13]2- cluster for noble metal-free visible light-driven hydrogen evolution within a polyampholytic matrix
We report on a photocatalytic setup that utilizes the organic photosensitizer (PS) diiodo-BODIPY and the non-precious-metal-based hydrogen evolution reaction (HER) catalyst (NH4)2[Mo3S13] together with...
Publications | 18.04.2023Cavity-enhanced field-resolved spectroscopy
Femtosecond enhancement cavities1 are key to applications including high-sensitivity linear2–4 and nonlinear5,6 gas spectroscopy, as well as efficient nonlinear optical frequency conversion7–10. Yet,...
Publications | 06.09.2022High-throughput Raman spectroscopy allows ex vivo characterization of murine small intestinal intra-epithelial lymphocytes (IEL)†
T cells are considered to be critical drivers of intestinal inflammation in mice and people. The so called intra-epithelial lymphocyte (IEL) compartment largely consist of T cells. Interestingly, the specific...
Publications | 03.04.2023Do lipids tune B cell signaling?
The role of lipid membrane domains in the activation of immune cells remains elusive. New microscopy data on B cell signalling support a mechanism in which lipid membrane domains consolidate upon B cell...
Publications | 03.04.2023Large-scale assembly and pattern transfer of SERS-active nanoparticles for application in drug monitoring of methotrexate in blood serum
Self-assembly of plasmonic gold nanoparticles (AuNPs) in periodic arrays with nanometric gaps results in the optimization of near- and far-field effects, which provides excellent surface-enhanced Raman...
Publications | 31.03.2023Multifocal hyperspectral Raman imaging setup for multi-well plates
High-throughput screening has become widespread in drug discovery. This increases the need for efficient, parallelized spectral imaging techniques. However, current designs focus on microplate readers...
Publications | 31.03.2023Step-by-step : A microfluidic (PDMS) staircase device for size sorting microparticles down to 25 μm using a 3D-printed mold
Microparticles are ubiquitous and span from living matter to microplastics to inorganic materials. Their detection and identification must be more accessible and time efficient. Microfluidic devices can...
Publications | 31.03.2023Enhancing on/off ratio of a dielectric-loaded plasmonic logic gate with an amplitude modulator
Plasmonic waveguides allow focusing, guiding, and manipulating light at the nanoscale and promise the miniaturization of functional optical nanocircuits. Dielectric-loaded plasmonic (DLP) waveguides and...
Publications | 28.03.2023Opportunities of optical and spectral technologies in intraoperative histopathology
Modern optical and spectral technologies represent powerful approaches for a molecular characterization of tissues enabling delineating pathological tissues but also a label-free grading and staging of...
