Biopolymer-encapsulated single-walled carbon nanotubes (SWNT) recognize specific nitroarom. mols. via either a wavelength or intensity change of near IR photoluminescence. A class of peptides from the bombolitin family not previously identified for nitroar ...
Infrared scanning near-field optical microscopy (IR-SNOM) is an extremely powerful analytical instrument since it combines IR spectroscopy's high chemical specificity with SNOM's high spatial resolution. In order to do this in the infrared, specialty chalc ...
This thesis comes within the scope of tribology studies at the nanometer scale. The experimental techniques used in this work are essentially related to atomic force microscopy, which gives a direct access to the topography and forces of the studied system ...
High-resolution detection of specific molecules in cells is a major challenge in biology. We show that infrared scanning near-field microscopy can detect the spatial distribution of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid–type glutamate r ...
This thesis presents the development of a scattering scanning near-field microscope (s-SNOM) and investigations on the photoluminescence study of solid C60. The first part concerns setting up of such a scattering SNOM where a tuning fork with an attached A ...
Spatial, energy, and time-dependent effects induced by surface charging of conductive and nonconductive samples have been studied by spectroscopic and microscopic techniques. Surface charging of indium-tin oxide and cesium iodide has been studied by atomic ...
Endoluminal microscopy and spectroscopy could significantly improve the efficiency of clinical endoscopic examination by allowing in-situ detection, staging and grading of potentially cancerous lesions. Indeed, high-end optical microscopy techniques such a ...
An epoxy-based negative-tone photoresist, which is known as a suitable material for high-aspect-ratio surface micromachining, is functionalized with red-light-emitting CdSe@ZnS nanocrystals (NCs). The proper selection of a common solvent for the NCs and th ...
NOVELTY - The microscope (11) has a set of four actuators (14, 16, 18, 20) i.e. piezoelectric actuators, and a strain gauge coupled to two opposed actuators (14, 18), arranged in opposed push or push-pull configuration to measure the differential motion of ...
We report fluorescence correlation spectroscopy (FCS) measurements using near-field scanning optical microscopy (NSOM) probes to produce a sub-diffraction-limited observation area. An order of magnitude reduction in the area compared to confocal FCS has be ...
