Scalable Chemical Tool for Analyzing Brain: Electron Microscope-Like Images with Fluorescent Microscope
… be achieved with FM (i.e., conventional light microscope), allowing anyone to identify and localize biomolecules in the detailed ultrastructural context of neural circuits. In this study, we report a novel membrane probe and modified expansion microscopy (ExM) protocol aimed at achieving …

Compressed fluorescence lifetime imaging microscope
Fluorescence lifetime imaging microscopy (FLIM) has been extensively applied in wide biomedical applications from single cell studies to medical diagnosis. While the state-of-the-art FLIM techniques are highly sensitive to biological dynamics such as fluorescence resonance emission transfer (FRET), …

A metrological atomic force microscope
… and testing of a metrological atomic force microscope (AFM). This design serves as a prototype for a similar system that will later be integrated with the Sub-Atomic Measuring Machine (SAMM) under development in collaboration with the University of North Carolina at Charlotte. The microscope …

Switchable stiffness scanning microscope probe
Atomic Force Microscopy (AFM) has rapidly gained widespread utilization as an imaging device and micro/nano-manipulator during recent years. This thesis investigates the new concept of a dual stiffness scanning probe with respect to biological applications and determines the resulting requirements …

Simulating scanning tunneling microscope measurements
One of the largest problems in scanning tunneling microscopy design is noise control. It is the burden of the designer to determine if money should be used to build a floating room for vibration isolation or for top-of-the-line preamplifiers that can be placed at low temperatures. This thesis …

A Vertical Coarse Approach Scanning Tunneling Microscope
A Pan-style scanning tunneling microscope (STM), with a vertical coarse approach mechanism, was designed, built and tested. The microscope will be operated in ultra-high vacuum and also at cryogenic temperatures (8 K) inside a continuous flow cryostat. Fundamental differences in operating principle …

GRAPHENE NANOSTUCTURING WITH THE HELIUM ION MICROSCOPE
NANO-ENGINEERING OF GRAPHENE HAS ATTRACTED TREMENDOUS INTEREST FOR GRAPHENE?S POTENTIAL APPLICATIONS. HOWEVER, THE CONVENTIONAL FABRICATION TECHNIQUES, ARE EITHER LIMITED BY THE LITHOGRAPHIC RESOLUTION OR LIMITED TO FIXED GEOMETRIES. OUR GROUP HAS DEMONSTRATED A RESIST-FREE DIRECT PATTERNING METHOD …

Molecular manipulation with the scanning tunnelling microscope
This thesis presents two studies into molecular manipulation using scanning tunnelling microscopy (STM), dissociation of chrolobenzene (PhCl) and of 4,4´ dichlorobiphenyl (PCB) manipulation both on Si(111)-7×7 surface. An ab initio investigation is presented on a possible candidate for future …

Content Based Image Retrieval From Microscope Slides
Finally I developed a variation of hierarchical clustering which I call connected clustering. It groups neighboring images that are similar, allowing the system to treat them as a single unit. I show that this improves the response time of the system and reduces redundancy in the results displayed …

Shock initiation of explosives under the microscope
This dissertation explores the shock compression of solid state explosives by thin, laser-driven flyer plates. These flyer plates consist of aluminum foils, typically 25 – 75 μm thick, which are launched using a Nd:YAG laser with a 20 ns pulse width in a technique developed within the Dlott group. …

Cytotoxic T lymphocyte biology under the microscope
Cytotoxic T lymphocytes (CTLs) are essential agents of the adaptive immune system that seek out and destroy virally infected or cancerous cells. Incapacitate them and you become severely immunocompromised and riddled with tumours (à la prf1-/- mouse model); enhance them and you can beat previously …

Tip steering of the Atomic Force Microscope.
The Atomic Force Microscope (AFM) is a powerful tool for the imaging of extremely small objects on the scale of nanometers, like carbon nanotubes and strands of DNA. There currently is a need for methods to actively steer the probe tip of the AFM in order to greatly reduce the time required to …

Metrics for Evaluating Surgical Microscope Usage During Myringotomy
Abstract Although teaching and learning surgical microscope manoeuvring is a fundamental step in middle ear surgical training, currently there is no objective method to teach or assess this skill. This thesis presents an experimental study designed to implement and test sets of metrics capable of …
