Magnetic and fluorescent core–shell nanoparticles for ratiometric pH sensing
This paper describes the preparation of nanoparticles (NPs) with a magnetic core surrounded by two successive silica shells embedding two fluorophores which allow ratiometric pH-measurments in the biologically...
PublikationenSensoric potential of gold-silver core-shell nanoparticles
The sensitivities of five different core-shell nanostructures were investigated towards changes in the refractive index of the surrounding medium. The shift of the LSPR maximum served as a measure of the...
PublikationenInvestigation of adhesive-dentin interfaces using Raman microspectroscopy and small angle X-ray scattering
Human dentin specimens were treated with two different etch-and-rinse adhesives, Single Bond 2 (SB2) and Prime bond NT (PBNT), and two composite resins, TPH and P60. Cross-sectional samples, approximately...
PublikationenComparison of numerical methods in near-field computation for metallic nanoparticles
Four widely used electromagnetic field solvers are applied to the problem of scattering by a spherical or spheroidal silver nanoparticle in glass. The solvers are tested in a frequency range where the...
PublikationenSpectral Unmixing and Clustering Algorithms for assessment of single cells by Raman Microscopic Imaging
A detailed comparison of six multivariate algorithms is presented to analyze and generate Raman microscopic images that consist of a large number of individual spectra. This includes the segmentation algorithms...
PublikationenNumerical and experimental investigations of mixing in T-shaped and cross-shaped micromixers
The mass transfer within the T-shaped and cross-shaped micromixers have been studied using the CFD and confocal laser scanning microscopy methods. The concentration profiles, based on flow regimes, were...
PublikationenOptical properties of metamaterials based on asymmetric double-wire structures
We performed theoretical and experimental investigations of the magnetic properties of metamaterials based on asymmetric double-wire structures. Using the multipole model for the description of metamaterials,...
PublikationenTumour cell identification by means of Raman spectroscopy in combination with optical traps and microfluidic environments
Raman spectroscopy has been recognized to be a powerful tool for label-free discrimination of cells. Sampling methods are under development to utilize the unique capabilities to identify cells in body...
PublikationenPeriodic Nanostructures: Spatial Dispersion Mimics Chirality
Polarization rotation in isotropic materials is commonly associated with chirality, i.e., structures with a handedness which are not identical with their mirror image. We observe this effect in the visible...
PublikationenDirect observation of temperature dependent excited-state equilibrium in dinuclear ruthenium terpyridine complexes bearing electron-poor bridging ligands
Dinuclear ruthenium-terpyridine complexes, bearing highly conjugated bridging ligands, have been investigated by time and temperature dependent emission spectroscopy, time-dependent density functional...
