Nonlinear microscopy, infrared and Raman microspectroscopy for brain tumor analysis
Scope of the neurosurgical management of brain tumors is to remove pathological tissue, preserve normal tissue and brain functions, and collect material for neuropathological diagnosis. A prerequisite...
PublikationenTemperature and Strain Sensing With Femtosecond Laser Written Bragg Gratings in Defect and Nondefect Suspended-Silica-Core Fibers
The spectral behavior in the C-band of Fiber Bragg Gratings (FBGs) was analyzed as a function of temperature and strain. The FBGs were fabricated in pure silica four-leaf clover shaped suspended-core fibers...
PublikationenMicrosegmented Flow-through Synthesis of Silver Nanoprisms with Exact Tunable Optical Properties
In this work, a multistep microcontinuous flow through synthesis procedure for the generation of homogeneous, high-quality silver nanoprisms is presented. The particle synthesis is based on the wet chemical...
PublikationenHigh performance uncooled THz sensing structures based on antenna-coupled air-bridges
Antenna-coupled sensing elements, microbolometers as well as thermocouples, are potential solutions in focal plane arrays (FPA). The applications for these lightweight and low-cost sensors are specified...
PublikationenHomogenous metallic nanoparticle monolayer inside a microstructured optical fiber
Proc. SPIE 8073, 80732J (2011); doi:10.1117/12.886846 Microstructured optical fibers (MOFs) represent a promising platform technology for new biosensing devices. Using MOFs with adapted cavity diameters...
PublikationenAll-fiber laser source for CARS microscopy based on fiber optical parametric frequency conversion
A novel approach for an all-fiber mono-laser source for CARS microscopy is presented. An Yb-fiber laser generates 100 ps pulses, which later undergo narrowband in-fiber frequency conversion based on degenerate...
PublikationenThe morphology of silver nanoparticles prepared by enzyme-induced reduction
Silver nanoparticles were synthesized by an enzymatic induced growth process onto solid substrates. In order to customize the enzymatically grown nanoparticles (EGNP) to analytical applications in bio-molecular...
PublikationenTracking of nanoscale structural variations on a single amyloid fibril with tip-enhanced Raman scattering
Amyloid fibrils are known to be responsible for diseases such as Alzheimer’s disease. A detailed insight into the structure of amyloid fibrils is fundamental since it is not yet understood what triggers...
PublikationenConcepts and steps for the realization of a new domain wall based device: from the available 24 multiturn counter to a 2power12 turn counter
Two concepts for new types of a magnetic domain wall based multiturn counter with true power on functionality are presented. Both counters use several closed loops of magnetic nanowires, each with different...
PublikationenThe morphology of Al-based submicron Josephson junction
We present a detailed study of the microstructure of submicron Al/Al−O/Al Josephson junctions fabricated by the conventional shadow evaporation technique. The morphology of the dielectric Al−O layer,...
