Preparation Technique of Antiresonant Hollow Core Microstructured Optical Fibers for Chemical Sensing
Hollow Core Microstructured Optical Fibers (HCMOFs) enable single mode guidance with large mode field diameters. HCMOFs can be applied for chemical sensing by filling the hollow core with appropriate analytes....
PublikationenOptical photon reassignment with increased axial resolution by structured illumination
Fluorescent microscopy methods linked to the reassignment principle as Image Scanning Microscopy (ISM), re-scan confocal, Optical Photon Reassignment (OPRA) and instant Structured Illumination Microscopy...
PublikationenHeme interacts with histidine- and tyrosine-based protein motifs and inhibits enzymatic activity of chloramphenicol acetyltransferase from Escherichia coli
Heme is a crucial constituent in the organization of many living organisms. The occurrence of free organismal heme can either contribute to serious diseases or beneficially regulate important physiological...
PublikationenInvestigated charge carrier effects in silicon membranes using a femtosecond laser
The second harmonic (SH) generated at the Si/SiO2 interface varies on a time scale of several seconds when illuminated with high intensity near infrared laser pulse trains (800 nm, 80 fs, 80MHz repetition...
PublikationenSupramolecular macrocycles reversibly assembled by Te…O chalcogen bonding
Organic molecules with heavy main-group elements frequently form supramolecular links to electron-rich centres. One particular case of such interactions is halogen bonding. Most studies of this phenomenon...
PublikationenEffective Photon Count Estimation from a Single Image Acquisition
Most image sensors do not directly report the actual number of detected photons per pixel, but instead a value generated after the photo-electrons registered on a physical sensor have passed through an...
PublikationenElectrically Excited Plasmonic Nanoruler for biomolecule detection
Plasmon based sensors are excellent tools for a label free detection of small biomolecules. An interesting group of such sensors are plasmonic nanorulers which relay on the plasmon hybridization upon modification...
PublikationenBeyond endoscopic assessment in inflammatory bowel disease: real-time histology of disease activity by non-linear multimodal imaging
Assessing disease activity is a prerequisite for an adequate treatment of inflammatory bowel diseases (IBD) such as Crohn’s disease and ulcerative colitis. In addition to endoscopic mucosal healing,...
PublikationenPhoto-Induced or Plasmon-Induced Reaction: Investigation of the Light-Induced Azo-Coupling of Amino Groups
The plasmon-mediated azo-coupling of p-aminothiophenol (PATP) and p-nitrothiophenol (pNTP) was recently achieved using gold and silver nanostructures with the help of hot electrons. To further investigate...
PublikationenToward Single Electron Nanoelectronics Using Self-Assembled DNA Structure
DNA based structures offer an adaptable and robust way to develop customized nanostructures for various bionanotechnological purposes. One main aim in this field is to develop a DNA nano-breadboard for...
