Localized surface plasmon resonance (LSPR) study of DNA hybridization at single nanoparticle transducers
The effect of DNA-DNA interaction on the localized surface plasmon resonance of single 80 nm gold nanoparticles is studied. Therefore, both the attachment of the capture DNA strands at the particle surface...
PublicationsAdvanced giant magnetoresistance technology for measurement applications
Giant magnetoresistance sensors are considered one of the first real applications of nanotechnology. They consist of nm-thick layered structures where ferromagnetic metals are sandwiched by nonmagnetic...
PublicationsRaman Spectroscopic Imaging for the Real-Time Detection of Chemical Changes Associated with Docetaxel Exposure
There is an urgent need for methods allowing for a fast, noninvasive, sensitive and selective monitoring of the effectiveness of anticancer drugs during the course of a chemotherapeutic treatment of cancer...
PublicationsRecent Developments in Superconductor Digital Electronics Technology at FLUXONICS Foundry
In Europe, the FLUXONICS Foundry develops fabrication processes and design-kits for superconductor digital and mixed-signal circuits. We describe the implementation of the “European Roadmap for Superconductor...
PublicationsPolyacrylamid/Silver Composite Particles Produced via Microfluidic Photopolymerization for Single Particle-Based SERS Microsensorics
A micro-continuous-flow process was applied for the preparation of swellable polyacrylamide particles incorporating silver nanoparticles. These sensor particles are formed from a mixture of a colloidal...
PublicationsChemical degradation mechanisms of highly efficient blue phosphorescent emitters used for organic light emitting diodes
The stability and the degradation processes of two highly efficient blue-emitting phosphorescent materials, iridium(III) bis(40,60-difluorophenylpyridinato)tetrakis(1-pyrazolyl) borate (FIr6) and bis(2-(4,6-difluorophenyl)...
PublicationsQuartz microfluidic chip for tumour cell identification by Raman spectroscopy in combination with optical traps
Three important technical innovations are reported here towards Raman-activated cell sorting. Firstly, a microfluidic chip made of quartz is introduced which integrates injection of single cells, trapping...
PublicationsRaman Scattering and Third-Harmonic Generation in Silicon Nanowire Ensembles
Experiments on Raman scattering and third-harmonic generation in silicon nanowire ensembles formed demonstrate one-order-of-magnitude rise of these signals in them in comparison with crystalline silicon,...
PublicationsSTXM and NanoSIMS investigations on EPS fractions before and after adsorption to goethite
Extracellular polymeric substances (EPS) are expected to be an important source for the formation of mineral-organic associations in soil. Since such formations affect the composition of mobile and immobile...
PublicationsEvidence of Tm impact in low-photodarkening Yb-doped fibers
In contrast to Yb/Al-doped fibers, the influence of very low Tm2O3 concentrations (≥ 0.1 mol-ppm) on photodarkening (PD) is clearly detectable in Yb/P-doped fibers that are known to show little degradation...
