Electrically-Tunable Multi-Wavelength Bragg Grating Filter Acoustically Induced in a Highly Birefringent Suspended Core Fiber
Multi-wavelength reflection spectra induced by an acoustically modulated fiber Bragg grating in a highly birefringent suspended core fiber are experimentally investigated. Longitudinal acoustic waves interacting...
PublikationenRaman spectroscopic imaging of human macrophages incubated with triglyceride-enriched oxLDL visualizes translocation of lipids between endocytic vesicles and lipid droplets
Raman spectroscopic imaging was used to investigate the uptake of oxidized low-density lipoproteins (oxLDL) by human macrophages. To better understand the receptor-mediated pathway and the intracellular...
PublikationenReal-time Raman and SRS imaging of living human macrophages reveals cell-to-cell heterogeneity and dynamics of lipid uptake
Monitoring living cells in real-time is important in order to unravel complex dynamic processes in life sciences. In particular the dynamics of initiation and progression of degenerative diseases is intensely...
PublikationenGrowth of Hierarchically 3D Silver-Silica Hybrid Nanostructures by Metastable State Assisted Atomic Layer Deposition (MS-ALD)
A novel, easy, two-step bottom-up fabrication strategy is introduced for the synthesis of 3D silver-silica hybrid nanostructures employing enzymatically generated silver nanoparticles (EGNPs) and plasma...
PublikationenEnergy vs. electron transfer – controlling the excitation transfer in molecular triads NUMBERS
The photochemistry of Ru(II) coordination compounds is generally discussed to originate from the lowest lying triplet metal-to-ligand charge-transfer state (3MLCT). However, when heteroleptic complexes...
PublikationenDiscretely tunable Tm-doped fiber-based MOPA using FBG arrays as spectral filters
Over the past years, Thulium (Tm) -doped fiber lasers in the 2μm region have gained a lot of interest due to many potential applications in materials processing and biophotonics. Based on the broad gain...
PublikationenProcess flow to integrate nanostructures on silicon grass in surface micromachined systems
The process flow to integrate metallic nanostructures in surface micromachining processes is presented. The nanostructures are generated by evaporation of microstructured silicon grass with metal. The...
PublikationenSynthesis and solution stability of water-soluble κ2N,κO-bis(3,5-dimethylpyrazolyl)ethanol manganese(I) tricarbonyl bromide (CORM-ONN1)
The reaction of (OC)5MnBr with bis(3,5-dimethyl-1-pyrazolyl)methane yields [{(PzMe2)2CH2}Mn(CO)3Br](1). The use of tridentate heteroscorpionates such as bis(3,5-dimethyl-1-pyrazolyl)acetic acid and 2,2-bis(3,5-dimethyl-1-pyrazolyl)ethanol...
PublikationenTip-enhanced Raman scattering for tracking of invasomes in the stratum corneum
Stratum corneum is the primary skin barrier to percutaneous absorption. Since 1980, topical liposomal formulations have been proposed and successfully employed for increasing the drug penetration through...
PublikationenChemical-Mechanically Planarized Cross-Type Josephson Junctions in Nb-Al-AlOx-Nb Technology
Fabrication of devices composed of Josephson junctions in trilayer technology is usually compromised by the topography of the subjacent layers. If the structures of subsequent layers traverse steps, several...
