Distribution of Amygdalin in Apricot (Prunus armeniaca) Seeds Studied by Raman Microscopic Imaging
Amygdalin is a cyanogenic glycoside found in the seeds of several plants belonging to the Rosaceae family. Cyanogenic glycosides can be specifically probed by Raman spectroscopy due to an inherent nitrile...
PublicationsDiagnosis of tumor cells by combination of Raman spectroscopy and microfluidics
Circulating epithelial tumor cells are of increasing importance for tumor diagnosis and therapy monitoring of cancer patients. The definite identification of the rare tumor cells within numerous blood...
PublicationsRaman and FTIR microspectroscopy for detection of brain metastasis
Vibrational spectroscopic imaging methods are novel tools to visualise chemical component in tissue without staining. Fourier transform infrared (FTIR) imaging is more frequently applied than Raman imaging...
PublicationsDevelopment of a fiber-based Raman probe for clinical diagnostics
A basic problem intrinsic to many clinical diagnostic procedures as well as minimally invasive surgeries is the online in-vivo classification of tissue. Associated with this problem is the task to determine...
PublicationsCharacterization of Atherosclerotic Plaque-Depositions by Infrared, Raman and CARS Microscopy
Arterial plaque-depositions that are associated with atherosclerosis are mainly composed of proteoglycans, triglycerides, cholesterol, cholesterolester and crystalline calcium. From histopathological characterizations...
PublicationsNonlinear 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...
PublicationsTemperature 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...
PublicationsMicrosegmented 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...
PublicationsHigh 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...
PublicationsHomogenous 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...
