Investigating drug induced changes in single, living lymphocytes based on Raman micro-spectroscopy
Raman spectroscopy is a powerful tool for label-free, single cell characterization. In many reported studies, a Raman spectrum is acquired from a fraction of the cell volume and used as a representative...
PublikationenCharacterization of collagen and cholesterol deposition in atherosclerotic arterial tissue using non-linear microscopy
Atherosclerosis is characterized by the accumulation of lipids within the arterial wall and is commonly diagnosed using standard histology. Non-linear microscopy represents a possible label-free alternative...
PublikationenPlasmonically Enhanced Electron Escape from Gold Nanoparticles and Their Polarization-Dependent Excitation Transfer along DNA Nanowires
Here we show plasmon mediated excitation transfer along DNA nanowires over up to one micrometer. Apparently, an electron excitation is initiated by a femtosecond laser pulse that illuminates gold nanoparticles...
PublikationenOptical properties of nanowire structures produced by the metal-assisted chemical etching of lightly doped silicon crystal wafers
Layers of silicon nanowires with diameters of 20−200 nm, grown by metal-assisted chemical etching of monocrystalline silicon substrates of p-type conductivity with a resistivity of 1−20Ohm · cm and...
PublikationenNanoparticles prepared from porous silicon nanowires for bio-imaging and sonodynamic therapy
Evaluation of cytotoxicity, photoluminescence, bio-imaging, and sono-sensitizing properties of silicon nanoparticles (SiNPs) prepared by ultrasound grinding of porous silicon nanowires (SiNWs) have been...
PublikationenSelf-healing mechanism of metallopolymers investigated by QM/MM simulations and Raman spectroscopy
The thermally induced self-healing mechanisms in metallopolymers based on bisterpyridine complexes of iron(II) sulfate and cadmium(II) bromide, respectively, were studied by means of combined quantum mechanical/molecular...
PublikationenHow to test the „quantumness“ of a quantum computer?
Recent devices, using hundreds of superconducting quantum bits, claim to perform quantum computing. However, it is not an easy task to determine and quantify the degree of quantum coherence and control...
PublikationenHigh power laser fiber fabricated through vapor phase doping of Ytterbium
We present the characteristics of an ytterbium-doped alumino-silicate fiber, fabricated through vapor phase doping of aluminum and ytterbium in the core, along with silica and in conjunction with the modified...
PublikationenToward high-throughput chip calorimetry by use of segmented-flow technology
The adaptation of segmented-flow technology to flow-through calorimetry was demonstrated by different kinds of newly designed chip calorimeters useful for liquids and suspensions as well as for solid samples....
PublikationenThermopile chip based calorimeter for the study of aggregated biological samples in segmented flow
We present the first silicon chip-based calorimeter with segmented-flow technology (SFT) for the study of solid and aggregated samples. Solid particles or biological aggregates up to 1.5 mm are immersed...
