Abstract:
This dissertation describes new methods for measuring surface forces using evanescent waves, and applications to non-DLVO forces. An evanescent wave, generated at a solid-liquid interface, is scattered by AFM tips or particles attached to AFM cantilevers. The scattering of this wave is used to determine absolute separation between surfaces and/or the refractive index as a function of separation in AFM measurements. This technique is known as evanescent wave atomic force microscopy (EW-AFM). The scattering of an evanescent wave by Si3N4 AFM tips is large and decays exponentially with separ

Abstract:
This thesis presents new paradigms for a particular class of non-prehensile manipulators of nanoscale objects that are limited to modelling accurately the relative motion of objects using continuous mechanics where the contact area is not presented. This restrictions results in models which have low accuracy and a lack of understanding about the real motion of the nanoscale object. The newly developed paradigms are focused on three topics: characterisation and analysis of forces present during motion at nanoscale in two dimensional space; characterisation and analysis of the quasi-static motio

The use of an AFM to manipulate a monolayer of thiols deposited on a gold substrate via nanografting is shown in our work to enable chemical modification of the surface of the substrate by varying the composition of the monolayer deposited on it.

Abstract:
The atomic force microscope (AFM) provides a powerful instrument for investigating and manipulating biological samples down to the subnanometer scale. In contrast to other microscopy methods, AFM does not require labeling, staining, nor fixation of samples and allows the specimen to be fully hydrated in buffer solution during the experiments. Moreover, AFM clearly compares in resolution to other techniques. In general, the AFM can be operated in an imaging or a force spectroscopy mode. In the present work, advantage was taken of this versatility to investigate single biomolecules and biomole

Membrane fusion is essential for survival in eukaryotic cells. Many physiological processes such as endocytosis and exocytosis are mediated by membrane fusion, which is driven by highly specialized and conserved family of proteins. Neuronal soluble Nethylmaleimide- sensitive factor attachment protein receptors (SNAREs) mediate vesicle fusion with the plasma membrane during neurotransmitter release; however, the mechanism for SNARE-mediated membrane fusion remains to be established. In the current work, we aimed at investigating this mechanism using atomic force microscope (AFM) spectroscopy. W

Abstract:
This study describes the covalent and the electrostatic attachment of molecules, nano-particles, and proteins to patterned self-assembled monolayers. A scanning probe nanografting technique was employed to produce patterns of various sizes, down to 10 nm. Thus, we are able to demonstrate a degree of surface patterning which is an order of magnitude smaller than that used in the semiconductor industry. One efficient strategy for creating chemically specific nanostructures is to use the extraordinary catalytic properties of enzymes. However, as the dimension of a catalyst patch is reduced down t

Abstract:
This thesis research focuses on the characterization of thinfilms made of poly(vinylidene fluoride) (PVDF) using an atomic force microscope. Thinfilms of PVDF were fabricated by a spin coating method with different conditions and characterized using the Atomic Force Microscopy (AFM) for morphological changes. Phase and conformational changes of PVDF were investigated using both wide angle X-ray diffraction (WAXD) and Fourier Transform Infrared Spectroscopy (FTIR). From this analysis, in-situ corona poling with annealing of spin-cast PVDF enabled a phase change from α to the mixture of β
