Classification of Raman spectra of single cells with autofluorescence suppression by wavelength modulated excitation
Wavelength modulated Raman spectroscopy has recently been shown to suppress the fluorescence background generated by the sample and the substrate. Here we apply this technique to collect wavelength modulated...
PublicationsHyperspectral unmixing of Raman micro-images for assessment of morphological and chemical parameters in non-dried brain tumor specimens
Hyperspectral unmixing is a group of unsupervised algorithms to calculate spectral endmembers and the abundances of components in Raman images. 39 Raman images were collected from six glioma brain tumor...
PublicationsCombination of Structured Illumination and Single Molecule Localization Microscopy in one Setup
We present a high resolution fluorescence microscope setup which combines the advantages of Structured Illumination Microscopy (SIM) with those of Single Molecule Localization Microscopy (SMLM) in a single...
PublicationsMultimodal mapping of human skin
Background The combination of CARS (coherent anti-Stokes Raman scattering), SHG (second harmonic generation) and TPEF (two photon excited fluorescence) imaging – referred to as multimodal imaging –...
PublicationsNon-linear Micro-Spectroscopy – new Ways to diagnose white Skin Cancer?
In diesem Beitrag wird das Potential der Kombination von kohärenter anti-Stokesscher Raman Streuung (CARS), zwei-Photonen angeregter Fluoreszenz (TPEF) und Frequenzverdopplung (SHG) für Detektion von...
PublicationsSilicon nanowire solar cells with radial p-n heterojunction on crystalline silicon thin films: light trapping properties
We present a concept for a core-shell silicon nanowire thin film solar cell showing perfect light trapping. Nanowires are wet chemically etched into a several µm thick laser-crystallized silicon thin...
PublicationsMulticrystalline silicon thin film solar cells based on a two-step liquid phase laser crystallization process
We present a technology for preparing multi¬crystalline silicon thin film solar cells based on laser crystalliz¬ation. The technology makes use of high rate electron beam evap¬oration of amorphous silicon...
PublicationsUltrasensitive Fiber Enhanced UV Resonance Raman Sensing of Drugs
Fiber enhanced UV resonance Raman spectroscopy is introduced for chemical selective and ultrasensitive analysis of drugs in aqueous media. The application of hollow-core optical fibers provides a miniaturized...
PublicationsFemtosecond laser diagnostics of the built-in electric field across the p+-Si/SiO2 interface and its ultrafast shielding
Ultrafast shielding of the built-in electric field E0 across the p+-Si/SiO interface of boron doped Si upon near infrared femtosecond (fs) laser pulse irradiation (73fs, 35GW/cm2 < Ipeak < 115 GW/cm...
PublicationsIdentification of water pathogens by Raman microspectroscopy
Legionella species can be found living in water mostly in a viable but nonculturable state or associated with protozoa and complex biofilm formations. Isolation and afterwards identification of these pathogens...
