In response to rising demand for high performance actuators to serve nano-technology, a linear ultrasonic motor was designed and constructed to verify its potential as a viable nano-actuator. After establishing the analytical model that elucidates the physics of the ultrasonic motor operation, experimental performance tests were conducted in a fully digital controlled real-time control environm...

Supramolecular protein assemblies offer novel nanoscale architectures with molecular precision and unparalleled functional diversity. A key challenge, however, is to create precise nano-assemblies of functional proteins with both defined structures and a controlled number of protein-building blocks. Here we report a series of supramolecular green fluorescent protein oligomers that are assembled...

Nanotechnology define the science and engineering providing entirely new tools and capabilities, concerned with the design, synthesis, characterization and application of materials and devices that have a functional organization in at least 1 dimension on the nanometer (one billionth of a meter) capable to interact with cells and tissues at a molecular sub cellular level with a high degree of f...

Pick-and-place of micro/nano sized objects means handling of very tiny and very different in properties objects having specific behavior. Besides formal requirements of assembly processes, the tools for controllable manipulation with these objects should not affect the examined micro/nano environment, i.e. should be “small and passive” in any sense. Despite of the recent progress, most availabl...

Three dimensional single particle trapping and manipulation is an outstanding challenge in various fields ranging from basic physics to life sciences. By monitoring the response of a trapped particle to a designed environment one can extract its characteristics. In addition, quantum dynamics of a spatially scanned well-known particle can provide environmental information. Precise tracking and p...

This dissertation presents a distributed-parameters base modeling framework for microcantilever (MC)-based force sensing and control with applications to nanomanipulation and imaging. Due to the widespread applications of MCs in nanoscale force sensing or atomic force microscopy with nano-Newton to pico-Newton force measurement requirements, precise modeling of the involved MCs is essential. Al...

In recent years, surface acoustic wave (SAW) devices have demonstrated great potentials and increasing applications in the manipulation of nano- micro-particles including biological cells with advantages label-free, high sensitivity accuracy. this letter, we introduce a novel tilted-angle SAW to optimise pressure inside microchannel for cancer-cell manipulation. The generation radiation force a...

Shape manipulation of nanowires is highly desirable in the construction of nanostructures, in producing free-standing interconnect bridges and as a building block of more complex functional structures. By introducing asymmetry in growth parameters, which may result in compositional or microstructural non-uniformity in the nanowires, thermal annealing can be used to induce shape modification of ...

Optical vortex trapping can allow the capture and manipulation of micro- and nanometre-sized objects such as damageable biological particles or particles with a refractive index lower than the surrounding material. However, the quest for nanometric optical vortex trapping that overcomes the diffraction limit remains. Here we demonstrate the first experimental implementation of low-power nano-op...
