Development of new classes of plasmon active nano-structures and their application in bio-sensing and energy guiding
Metal nanostructures exhibit special optical resonance modes originating from the subwavelength confinement of conductive electrons in the material. These resonance modes represent a strong research focus...
PublicationsRemoval of step-edges and corresponding Gibbs ringing in SQUID-based geomagnetic data
We present a reliable post processing routine for the elimination of step-edges in SQUID-based geomagnetic data. A special feature of the algorithm is the correction of the A/D converters step response...
PublicationsAutomated seeding-based nuclei segmentation in nonlinear optical microscopy
Nonlinear optical (NLO) microscopy based, e. g., on coherent anti-Stokes Raman scattering (CARS) or two photon excited fluorescence (TPEF) is a fast label-free imaging technique, with a great potential...
PublicationsSERS-based detection of biomolecules
In order to detect biomolecules, different approaches using for instance biological, spectroscopic or imaging techniques are established. Due to the broad variety of these methods, this review is focused...
PublicationsLabeling of the Pathogenic Bacterium Staphylococcus aureus with Gold or Ferric Oxide-Core Nanoparticles Highlights New Capabilities for Investigation of Host-Pathogen Interactions
Throughout the world, infections caused by bacteria such as Staphylococcus aureus are a major cause of morbidity and mortality. In order to gain some understanding of the complicated physiological link...
PublicationsSurface Characterization of Insulin Protofilaments and Fibril Polymorphs Using Tip-Enhanced Raman Spectroscopy (TERS)
Amyloid fibrils are β-sheet rich protein aggregates that are strongly associated with a variety of neurodegenerative maladies, such as Alzheimer’s and Parkinson’s diseases. Even if the secondary structure...
PublicationsUV resonance Raman spectroscopy as an identification tool for pathogenic Candida samples
NUR Abstract von Poster P8: Vibrational spectroscopic techniques like, e.g. IR absorption or Raman spectroscopy are alternatives to conventional microbiological identification methods. Vibrational spectroscopy...
PublicationsControl of the Crystal Phase Composition of FexOy Nanopowders Prepared by CO2 Laser Vaporization
Crystalline magnetic iron oxide nanopowders are prepared by CO2 laser vaporization (LAVA) of a hematite (a-Fe2O3) raw powder. Condensation at normal pressure leads to maghemite (g-Fe2O3) as the main phase...
PublicationsRemote PCF-based sensors multiplexing by using optical add-drop multiplexers
A 100 km remote PCF micro-displacement sensor multiplexing system based on optical add-drop multiplexers (OADM) has been experimentally demonstrated. The PCF sensors are placed in an OADM bus structure...
PublicationsEnhanced Raman Scattering of Graphene using Arrays of Split Ring Resonators
Combining graphene with plasmonic nanostructures is currently being explored for high sensitivity biochemical detection based on the surfaceenhanced Raman scattering (SERS) effect. Here, a novel and tunable...
