Phase formation and magnetic properties of CoFe2O4/CoFe2 nanocomposites
Nanosize CoFe2O4 particles were synthesized via thermal decomposition of a mixed oxalate precursor; a mean ferrite particle size of 5 nm to 35 nm is tailored through variations of the decomposition temperature....
PublikationenUV-Raman spectroscopic identification of fungal spores important for respiratory diseases
Fungal spores are one of several environmental factors responsible for causing respiratory diseases like asthma ,chronic obstructive pulmonary disease (COPD), and aspergillosis. These spores also are able...
PublikationenA SERS-based molecular sensor for selective detection and quantification of copper(II) ions
A novel SERS-based molecular sensor for detection and quantification of copper(II) ions with very good specificity and selectivity is reported in this work. The sensing is enabled by the employment of...
PublikationenSignal, noise, and resolution in linear and nonlinear structured-illumination microscopy
Structured-illumination microscopy allows wide field fluorescence imaging with resolution beyond the classical diffraction limit. Its linear form extends resolution by a factor of two, and its nonlinear...
PublikationenObservation of Giant Infrared Circular Dichroism in Plasmonic 2D-Metamaterial Arrays
We report the observation of an enormous circular dichroism (CD) response in broadband surface enhanced infrared absorption sensing arrays. In our experiment, a 2D-metamaterial chiral cross-slit array...
PublikationenThe application of UV Resonance Raman spectroscopy for the differentiation of clinically relevant Candida species
Background: Candida-related infections have become a major problem in hospitals. The species identification of yeast is the prerequisite for the initiation of adequate antifungal therapy. Objectives: In...
PublikationenCalibrating photon counts from a single image
Most image capturing devices do not directly report the number of detected photons, but a value proportional to the photoelectron charge produced in a photomultiplier tube or collected in a camera pixel....
PublikationenUsing machine-learning to optimize phase contrast in a low-cost cellphone microscope
Cellphones equipped with high-quality cameras and powerful CPUs as well as GPUs are widespread. This opens new prospects to use such existing computational and imaging resources to perform medical diagnosis...
PublikationenRemoving interference-based effects from the infrared transflectance spectra of thin films on metallic substrates: A fast and wave optics conform solution
A hybrid formalism combining elements from Kramers-Kronig based analyses and dispersion analysis was developed, which allows correcting artefacts arising from electric field standing wave effects in the...
PublikationenSlit-Enhanced Chiral- and Broadband Infrared Ultra-Sensing
This work demonstrates a membrane-based chiralplasmonic metamaterial with two plasmonic absorption bandswhich can be used for broadband surface-enhanced infrared absorption (SEIRA) and vibrational circular...
