Near Field Scanning Optical Microscopy (NSOM) of nano devices
… of Near-Field Scanning Optical Microscopy (NSOM). A unique setup to perform Atomic Force Microscopy (AFM) and NSOM simultaneously in a scanning electron microscope (SEM) to collect spatially resolved luminescence and image transport on nano-scale structures, particularly nanowires, will …

Investigation of optical near field using near field scanning optical microscopy
… The Near Field Scanning Optical Microscopy (NSOM) has been developed to tackle certain aspects of this problem. The work presented here applies different types of NSOM to explore the near field distribution of metal plasmonic nanostructures.^ Ridge apertures with shapes like bowtie and C can …

Structure and Dynamic Studies of the Nuclear Pore Complex at the Single-Molecule Level
… near-field scanning optical microscopy (NSOM) are utilized to specifically locate vault ribonucleoproteins to NPCs. This interaction, along with several other results, strongly suggests that vaults represent the central mass of NPCs. A single-molecule transport assay was also developed in …

Thin film integrated optical waveguides for biosensing using local evanescent field detection
… films of patterned photoresist was found using NSOM. Light intensity measured at the surface of the .sample showed significant response to the presence of the photoresist features. Light response to a protein affinity assay was found and results indicated that protein concentration could be …

Toward an active CMOS electronics-photonics platform based on subwavelength structured devices
… Near-field scanning optical microscopy (NSOM) with a flip-chip post-processing technique, this dissertation demonstrates a method to non-invasively perform NSOM scans of a photonic device within a large-scale CMOS-photonic circuit, without interfering with the performance and packaging of …

Chiral expression at the nanoscale origin and recognition of chirality
… microscopy, circular dichroism spectroscopy and NSOM. The small enantiomeric excess achieved in experiments was explained by the limits of chirality determination methods. It was found that crystals formed in enantiomeric excess were of opposite chirality to the SAM they were grown on. This …

Evaluating Risks and Mitigation Measures for Foodborne Pathogens on Harvest Bags
Tree fruit growers need information on pathogen dynamics following harvest bags contamination to determine effective sanitation interventions for decontaminating these surfaces. Therefore, the objectives of this research were (i) to determine the survival of generic E. coli, Salmonella, and L. …

An experimental study of light-material interaction at subwavelength scale
… Using near-field scanning optical microscope (NSOM), I have experimentally studied light transmission through a subwavelength hole, and found an unusually large amount of phase shift in the transmitted light contradicting Bethe’s theory. Such effect is explained by the strong contribution of …

Formation of three-dimensional graphene structures by controlled thermal activation of polymeric shape memory substrates
This thesis details methodologies for a single-step approach to realise heterogeneous, three-dimensional (3D) texturing of graphene and graphite by using thermally-activated shape-memory polymers as the underlying substrate and the material characterizations thereof. Uniform, large area arrays of …

Optische Strukturierung ultradünner funktioneller Polymerfilme
Im Rahmen dieser Arbeit wurde die Strukturierbarkeit ultradünner, funktioneller Polymerfilme anhand von Diazosulfonat-Terpolymer- und Aminoterpolymer-Schichten untersucht. Beide Polymersysteme enthalten eine photoaktive Gruppe in der Seitenkette, die sich durch gezielte UV-Bestrahlung verändern …

Scattering Scanning Near-Field Optical Microscopy on Anisotropic Dielectrics
Near-field optical microscopy allows the nondestructive examination of surfaces with a spatial resolution far below the diffraction limit of Abbe. In fact, the resolution of this kind of microscope is not at all dependent on the wavelength, but is typically in the range of 10 to 100 nanometers. On …
