TopUp 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)....
PublicationsAnalytic 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...
PublicationsApplication 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....
PublicationsThe 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...
PublicationsRaman 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...
PublicationsPreparation Technique of Antiresonant Hollow Core Microstructured Optical Fibers for Chemical Sensing
Hollow Core Microstructured Optical Fibers (HCMOFs) enable single mode guidance with large mode field diameters. HCMOFs can be applied for chemical sensing by filling the hollow core with appropriate analytes....
PublicationsOptical photon reassignment with increased axial resolution by structured illumination
Fluorescent microscopy methods linked to the reassignment principle as Image Scanning Microscopy (ISM), re-scan confocal, Optical Photon Reassignment (OPRA) and instant Structured Illumination Microscopy...
PublicationsHeme interacts with histidine- and tyrosine-based protein motifs and inhibits enzymatic activity of chloramphenicol acetyltransferase from Escherichia coli
Heme is a crucial constituent in the organization of many living organisms. The occurrence of free organismal heme can either contribute to serious diseases or beneficially regulate important physiological...
PublicationsInvestigated charge carrier effects in silicon membranes using a femtosecond laser
The second harmonic (SH) generated at the Si/SiO2 interface varies on a time scale of several seconds when illuminated with high intensity near infrared laser pulse trains (800 nm, 80 fs, 80MHz repetition...
PublicationsSupramolecular macrocycles reversibly assembled by Te…O chalcogen bonding
Organic molecules with heavy main-group elements frequently form supramolecular links to electron-rich centres. One particular case of such interactions is halogen bonding. Most studies of this phenomenon...
