Diagnosis and screening of cancer tissue by fiber optic probe Raman spectroscopy
Raman spectroscopy is an emerging biophotonic tool that advanced in recent years due to steady improvements in instrumentation for excitation and collection, and the availability of fiber optic probes....
PublicationsFiber-Optical High-Resolution Esophagus Manometry Based on Fiber Bragg Gratings
We present a concept for improved distributed pressure measurements in medical applications using a multiplexed fiber Bragg grating array. A well-designed soft plastic coating mantle around an optical...
PublicationsHybrid Fe3O4@amino cellulose nanoparticles in organic media – Heterogeneous ligands for atom transfer radical polymerizations
We demonstrate an efficient strategy for the preparation of well-dispersed hybrid particles in organic media via a combination of the solution-based formation of magnetic nanoparticles (MNP)...
PublicationsAsymmetric flow field-flow fractionation of superferrimagnetic iron oxide multicore nanoparticles
Magnetic nanoparticles are very useful for various medical applications whereas each application requires particles with specific magnetic properties. In this contribution we describe the modification...
PublicationsA Microfluidic Spiral for Size-Dependent Fractionation of Magnetic Microspheres
Magnetic microspheres (MMS) are useful tools for a variety of medical and pharmaceutical applications. Typically, commercially manufactured MMS exhibit broad size distributions. This polydispersity is...
PublicationsCatalytic Efficiency of a Photoenzyme—An Adaptation to Natural Light Conditions
Cheap and safe: The catalytic efficiency of a light-dependent photoenzyme (NADPH: protochlorophyllide oxidoreductase) is investigated as a function of the excitation wavelength (see picture). It becomes...
PublicationsRaman spectroscopic determination of norbixin and tartrazine in sugar
In this paper, a method for the detection of norbixin and tartrazine in sugar by means of resonance Raman spectroscopy is presented. The extraction was done in four steps using methanol and the measurements...
PublicationsSpark plasma synthesis and sintering of superconducting MgB2-based materials
Superconducting (SC) and mechanical properties of spark plasma (or SPS) produced MgB2 –based materials allow their efficient applications in fault current limiters, superconducting electromotors, pumps,...
PublicationsMeasuring AC losses and critical current of high pressure synthesized MgB2 bulk rings by the transformer method
The results of experimental study of the critical current and AC losses in high pressuresynthesized MgB2 bulk superconductors are presented. The method is based on the use of the transformer configuration...
PublicationsRadial heteroemitter solar cells based on VLS grown silicon nanowires
Silicon nanowires (SiNWs) are an interesting system for the realization of solar cells, as they offer an enhanced light absorption compared to bulk Si. However, due to their large surface, nanowire solar...
