Cell identification using Raman spectroscopy in combination with optical trapping
Cell identification by Raman spectroscopy has evolved to be an attractive complement to established optical techniques. Raman activated cell sorting (RACS) offers prospects to complement the widely applied...
PublicationsMicrofluidically supported biochip design for culture of endothelial cell layers with improved perfusion conditions
Hemodynamic forces generated by the blood flow are of central importance for the function of endothelial cells (ECs), which form a biologically active cellular monolayer in blood vessels and serve as a...
PublicationsTowards TiO2-Ag porous nanocomposites based SERS sensors for chemical pollutant detection
Since the TiO2 environmental friendly character and the affinity of a large variety of molecules to bind to the silver surfaces are well-known, novel porous nanoarchitectures based on TiO2 aerogel and...
PublicationsSuspended Ring-Core Photonic Crystal Fiber Gas Sensor With High Sensitivity and Fast Response
We demonstrate design and fabrication of an in-line evanescent field gas sensor based on a novel suspended ring core photonic crystal fiber (PCF) to further overcome limitations in sensing capability....
PublicationsOrigins of modal loss of antiresonant hollow-core optical fibers in the ultraviolet
Recently, a novel antiresonant hollow core fiber was introduced having promising UV guiding properties. Accompanying simulations predicted ten times lower loss than observed experimentally. Increasing...
PublicationsLabel-Free Imaging and Spectroscopic Analysis of Intracellular Bacterial Infections
Staphylococcus aureus is one of the most frequent human pathogens that can also act as a facultative intracellular pathogen causing infections that are extremely difficult to treat. Only little is known...
PublicationsDetection of vancomycin resistances in enterococci within 3 1/2 hours
Vancomycin resistant enterococci (VRE) constitute a challenging problem in health care institutions worldwide. Novel methods to rapidly identify resistances are highly required to ensure an early start...
PublicationsUltrafast Intramolecular Relaxation and Wave-Packet Motion in a Ruthenium-Based Supramolecular Photocatalyst
The hydrogen-evolving photocatalyst [(tbbpy)2Ru(tpphz)Pd(Cl)2]2+ shows excitation-wavelength dependent catalytic activity, which was correlated to the localization of the initial excitation within the...
PublicationsFast structured illumination microscopy (fast SIM)
Structured Illumination Microscopy (SIM) distinguishes itself from the other super-resolution techniques by its potentially much faster imaging rate. However it requires the acquisition of several frames,...
PublicationsOptical Sectioning and High Resolution in Single-Slice Structured Illumination Microscopy by Thick Slice Blind-SIM Reconstruction
The microscope image of a thick fluorescent sample taken at a given focal plane is plagued by out of focus fluorescence and diffraction limited resolution. In this work, we show that Structured Illumination...
