Quantification of the fluorescence sensing performance of microstructured optical fibers compared to multi-mode fiber tips
Microstructured optical fibers, particularly those with a suspended-core geometry, have frequently been argued as efficient evanescent-field fluorescence-based sensors. However, to date there has not been...
PublikationenInfluence of Protonation State on the Excited State Dynamics of a Photobiologically Active Ru (II) Dyad
The influence of ligand protonation on the photophysics of a ruthenium (Ru) dyad bearing the 2-(1-pyrenyl)-1H-imidazo[4,5-f][1,10]-phenanthroline (ippy) ligand was investigated by using time-resolved transient...
PublikationenNoise-corrected principal component analysis of fluorescence lifetime imaging data
Fluorescence Lifetime Imaging (FLIM) is an attractive microscopy method in the life sciences, yielding information on the sample otherwise unavailable through intensity-based techniques. A novel Noise-Corrected...
PublikationenNonlinear structured illumination using a fluorescent protein activating at the readout wavelength
Structured illumination microscopy (SIM) is a wide-field technique in fluorescence microscopy that provides fast data acquisition and two-fold resolution improvement beyond the Abbe limit. We observed...
PublikationenOctave-spanning supercontinuum generation in hybrid silver metaphosphate/silica step-index fibers
We reveal the potential of step-index fibers consisting of a metaphosphate glass core and a silica claddingas ultrafast octave-spanning supercontinuum source.The hybrid waveguide was fabricated by pressureassisted...
PublikationenTopUp plasmonic arrays for surface enhanced Raman spectroscopy
By combining a bottom-up process with top-down fabricated templates, the benefits of both methods are joined by creating so-called TopUp plasmonic arrays for surface-enhanced Raman spectroscopy (SERS)....
PublikationenAnalytic model for the complex effective index dispersion of metamaterial-cladding large-area hollow core fibers
We present a mathematical model that allows interpreting the dispersion and attenuation of modes in hollow-core fibers (HCFs) on the basis of single interface reflection, giving rise to analytic and semi-analytic...
PublikationenApplication of quercetin and its bio-inspired nanoparticles as anti-adhesive agents against Bacillus subtilis attachment to surface
The aim of this study was directed to reveal the effect of quercetin and its bio-inspired titanium oxide and tungsten oxide nanoparticles on adhesion and subsequent biofilm formation of Bacillus subtilis....
PublikationenThe interaction of an amino-modified ZrO2 nanomaterial with macrophages – an in situ investigation by Raman microspectroscopy
Metal oxide nanoparticles (NP) are applied in the fields of biomedicine, pharmaceutics, and in consumer products as textiles, cosmetics, paints, or fuels. In this context, the functionalization of the...
PublikationenRaman spectroscopic identification of Mycobacterium tuberculosis
In this study, Raman microspectroscopy has been utilized to identify mycobacteria to the species level. Because of the slow growth of mycobacteria, the per se cultivation independent Raman microspectroscopy...
