Lab-on-a-chip-surface enhanced raman scattering combined with the standard addition method: toward the quantification of nitroxoline in spiked human urine samples
The emergence of antibacterial resistance and the development of new drags, lead to a continuous change of guidelines for medical treatments. Hence, new analytical tools are required for the detection...
PublikationenHD DVD substrates for surface enhanced Raman spectroscopy analysis: fabrication, theoretical predictions and practical performance
Commercial HD DVDs provide a characteristic structure of encoding pits which were utilized to fabricate cost efficiently large area SERS substrates for chemical analysis. The study targets the simulation...
PublikationenSmith-Purcell radiation in the terahertz regime using charged particle beams from laser-matter interactions
We report on the experimental observation of Smith-Purcell (SP) radiation generation by charged particle beam from laser-matter interactions. High-power laser pulses were focused onto a thin metal foil...
PublikationenUV-transparent fluoropolymer fiber coating for the inscription of chirped Bragg gratings arrays
A fluoropolymer optical fiber coating based on the thermoplastic copolymer of chlorotrifluoroethylene and vinylidene fluoride is presented. Such coatings can be used as a UV-transparent material for writing...
PublikationenTotal temperature measurement of fast air streams with fibre-optic Bragg grating sensors
The suitability of using fibre Bragg gratings (FBG) as sensor elements in total temperature probes for turbine compressor applications is shown. A series of five FBG-based probes were built and characterized...
PublikationenDeconvolution approach for 3D scanning microscopy with helical phase engineering
RESCH (REfocusing after SCanning using Helical phase engineering) microscopy is a scanning technique using engineered point spread functions which provides volumetric information. We present a strategy...
PublikationenPseudo-HE images derived from CARS/TPEF/SHG multimodal imaging in combination with Raman-spectroscopy as a pathological screening tool
Background: Due to the steadily increasing number of cancer patients worldwide the early diagnosis and treatment of cancer is a major field of research. The diagnosis of cancer is mostly performed by an...
PublikationenSERS as an analytical tool in environmental science: The detection of sulfamethoxazole in water in the nanomolar range by applying a microfluidic cartridge setup
Sulfamethoxazole (SMX) is a commonly applied antibiotic for treating urinary tract infections; however, allergic reactions and skin eczema are known side effects that are observed for all sulfonamides....
PublikationenZnO nanoflowers-based photoanodes: Aqueous chemical synthesis, microstructure and optical properties
We have developed an efficient, low temperature, synthetic route for ZnO nanoflowers(NFs) as photoanode material. This alternative route yields small flower-like nanostructures, built from densely self-assembled...
PublikationenNearly quantum limited nanoSQUIDs based on cross-type Nb/AlOx/Nb junctions
We report on the development of nearly quantum limited SQUIDs with miniature pickup loop dimensions. The implemented high quality and low capacitance cross-type Nb/AlOx/Nb Josephson junctions offer large...
