In situ excimer laser irradiation as cleaning tool for solid phase epitaxy of laser crystallized polycrystalline silicon thin films
This study demonstrates an innovative approach to clean a polycrystalline seed layer surface for solid phase epitaxy of amorphous silicon (a-Si). The excimer laser cleaning (ELC) makes use of in situ excimer...
PublicationsFörster Resonance Energy Transfer in Poly(methyl methacrylates) Copolymers Bearing Donor-Acceptor 1,3-Thiazole Dyes
The Förster resonance energy transfer (FRET) properties in poly(methyl methacrylate) copolymers containing 2-(pyridine-2-yl) thiazole dyes were studied upon systematic variation of the donor-to-acceptor...
PublicationsMonitoring the chemistry of self-healing by vibrational spectroscopy – current state and perspectives
Self-healing materials are designed to heal damage caused by, for example, mechanical stress or corrosion such that the original functionality of the material is at least partially restored. Thus, self-healing...
PublicationsAutomatic Identification of Novel Bacteria using Raman Spectroscopy and Gaussian Processes
Raman spectroscopy is successfully used for the reliable classification of complex biological samples. Much effort concentrates on the accurate prediction of known categories for highly relevant tasks...
PublicationsQuantification of the inorganic phase of the pelagic aggregates from an iron contaminated lake by means of Raman spectroscopy
A semi-quantitative investigation of the inorganic phase of pelagic, iron-rich aggregates (iron snow, IS) formed in an iron polluted aquatic environment was performed by means of Raman spectroscopy. IS...
PublicationsIntrinsic relaxation rates of polarized Cs vapor in miniaturized cells
The intrinsic relaxation rates of the vector magnetization of cesium vapor enclosed in microfabricated atomic magnetometer cells are investigated. Two methods - the optically detected magnetic resonance...
PublicationsIsolation and Enrichment of Pathogens with a Surface Modified Aluminium-Chip for Raman Spectroscopic Applications
We developed a Raman-compatible chip for isolating microorganisms from complex media. The isolation of bacteria is achieved by using antibodies as capture molecules. Due to the very specific interaction...
PublicationsDemonstration of amplified data transmission at 2 μm in a low-loss wide bandwidth hollow core photonic bandgap fiber
The first demonstration of a hollow core photonic bandgap fiber suitable for high-rate data transmission in the 2 μm waveband is presented. The fiber has a record low loss for this wavelength region (4.5...
PublicationsConvenient detection of E. coli in Ringer’s solution
An easy and inexpensive detection method for DNA hybridization assays combining magnetic beads and enzymatically generated silver nanoparticles is introduced. The main advantage of this approach is the...
PublicationsOptical Readout of a Nanoparticle Based Sensor by Cavity Ring-Down Spectroscopy
We combine the plasmonic properties of metallic nanoparticles enabling a label-free bioanalytical approach with the cavity ring-down method (CRD) in a miniaturized fluidic device as a sensitive and fast...
