This study showcases two independent magnetic manipulation systems to remotely control the movement of Fe3O4 nanomaterial in microfluidic chips. One system utilizes a homogeneous rotating magnetic field to carry out magnetic stirring in 100 μm and 300 μm flow channels. The mixing results of this system revealed that adding Fe3O4 nanoparticles to the solution enhances the efficiency of the micromixer by twice as much that of a device without the nanomaterial. The second manipulation system utilizes oscillating magnetic field for rapid microablation of thrombus in a microchannel. A customizable magnetic platform using 3D-printed material is also constructed. This is proposed as a feasible low-cost and portable magnetic manipulation device that can implement both applications.

Magnetic navigation systems (MNSs) have been developed to use in the diagnosis of gastrointestinal problems. However, most conventional magnetic navigation systems are expensive and have structural problems because of their large weights and volumes. Therefore, this paper proposes C-Mag, a novel compact MNS composed of two electromagnets and a robotic arm. The two electromagnets generate a planar magnetic field, and the robotic arm rotates and translates the electromagnets to manipulate the magnetic capsule in a large 3-dimensional (3-D) space. The C-Mag design considers the payload of the robotic arm and the capacity of the power supply unit. Under these limited conditions, the C-Mag was optimized to generate the maximum magnetic field considering several major factors. Finally, the C-Mag was constructed, and the maximum magnetic field that could be generated in one direction was 18.65 mT in the downward direction. Additionally, the maximum rotating magnetic field was 13.21 mT, which was used to manipulate the capsule. The performance was verified by measuring the generated magnetic field, and it matched well with the simulated result. Additionally, the path-following experiment of the magnetic capsule showed that the proposed C-Mag can effectively manipulate the magnetic capsule in 3-D space using the robotic arm. This study is expected to contribute to the further development of magnetic navigation systems to treat gastrointestinal problems.

Manipulation systems using magnetic field gradients have the ability to apply a large range of forces noninvasively to a specific target. Depending on the requirements of a given experiment, the systems may be as simple as a single electromagnet for unidirectional manipulation or as complex as a high-frequency three-dimensional manipulator with force feedback. Here, we discuss the motivation for developing such systems, theory and design considerations, and give examples of the broad range of manipulators that has been put to use. In addition, we discuss a variety of applications demonstrating the range of experiments for which such a system is applicable.

Swimming microrobots that are energized by external magnetic fields exhibit a variety of intriguing collective behaviors, ranging from dynamic self-organization to coherent motion; however, achieving multiple, desired collective modes within one colloidal system to emulate high environmental adaptability and enhanced tasking capabilities of natural swarms is challenging. Here, we present a strategy that uses alternating magnetic fields to program hematite colloidal particles into liquid, chain, vortex, and ribbon-like microrobotic swarms and enables fast and reversible transformations between them. The chain is characterized by passing through confined narrow channels, and the herring school–like ribbon procession is capable of large-area synchronized manipulation, whereas the colony-like vortex can aggregate at a high density toward coordinated handling of heavy loads. Using the developed discrete particle simulation methods, we investigated generation mechanisms of these four swarms, as well as the “tank-treading” motion of the chain and vortex merging. In addition, the swarms can be programmed to steer in any direction with excellent maneuverability, and the vortex’s chirality can be rapidly switched with high pattern stability. This reconfigurable microrobot swarm can provide versatile collective modes to address environmental variations or multitasking requirements; it has potential to investigate fundamentals in living systems and to serve as a functional bio-microrobot system for biomedicine.

Nitrogen-vacancy (NV) centers in diamonds play a large role in advanced quantum sensing with solid-state spins for potential miniaturized and portable application scenarios. With the temperature sensitivity of NV centers, the temperature fluctuations caused by the unknown environment and the system itself will mix with the magnetic field measurement. In this research, the temperature-sensitive characteristics of different diamonds, alongside the temperature noise generated by a measurement system, were tested and analyzed with a homemade NV magnetometer in a fiber-optic scheme. In this work, a multi-frequency synchronous manipulation method for resonating with the NV centers in all axial directions was proposed to compensate for the temperature fluctuations in a fibered NV magnetic field sensing scheme. The symmetrical features of the resonance lines of the NV centers, the common-mode fluctuations including temperature fluctuations, underwent effective compensation and elimination. The fluorescence change was reduced to 1.0% by multi-frequency synchronous manipulation from 5.5% of the single-frequency manipulation within a ±2 °C temperature range. Additionally, the multi-frequency synchronous manipulation improved the fluorescence contrast and the magnetic field measurement SNR through an omnidirectional manipulation scheme. It was very important to compensate for the temperature fluctuations, caused by both internal and external factors, to make use of the NV magnetometer in fiber-optic schemes’ practicality. This work will promote the rapid development and widespread applications of quantum sensing based on various systems and principles.

Age-related visual loss and ageing demographics account for a large impact on societal health costs on a global scale. Efficient ocular surgery must be precise, safe and cost effective. Current research focuses on robotic systems to assist in ophthalmic surgery. Furthermore, several platforms for drug delivery in the posterior segment of the eye have been introduced. Moreover, magnetic manipulation of tethered and untethered structures has been suggested to assist in teleoperated ophthalmic surgery and targeted drug delivery in the posterior eye due to its many advantages. Magnetic manipulation systems generate magnetic fields and gradients to guide magnetic objects with high precision and force feedback. A hybrid actuation system for guiding a flexible catheter with a sharp edge magnetic tip has been introduced for capsulorhexis a major step in cataract surgery. Research has demonstrated the potential of wireless magnetic microrobots for targeted drug delivery and simple mechanical operations in the posterior eye segment inex vivoandin vivoexperiments.

This thesis presents some experimental work in the area of manipulation of microparticles. Manipulation of both magnetic and non magnetic beads as well as microorganisms are addressed. The work on magnetic bead manipulation is focused on controlled transport and release, on a micrometer level, of proteins bound to the bead surface. Experimental results for protein transport and release using a method based on magnetization/demagnetization of micron-sized magnetic elements patterned on a modified chip-surface are presented. Special attention has been placed on minimizing bead-surface interactions since sticking problems have shown to be of major importance when protein-coated beads are used. The work with non-magnetic microparticles is focused on the dielectrophoretic manipulation of microorganisms. Preliminary experimental results for trapping and spatial separation of bacteria, yeast and non-magnetic beads are presented. The overall goal was to investigate the use of dielectrophoresis for the separation of sub-populations of bacteria differing in, for example, protein content. This was, however, not possible to demonstrate using our methods.Within the non-magnetic microparticle work, a method for determining the conductivity of bacteria in bulk was also developed. The method is based on the continuous lowering of medium conductivity of a bacterialsuspension while monitoring the medium and suspension conductivities.

Robust manipulation capture and retargeting has been a longstanding goal in both the fields of animation and robotics. In this thesis I describe a new approach to capture both the geometry and motion of interactions with objects, dealing with the problems of occlusion by the use of magnetic systems, and performing the reconstruction of the geometry by an RGB-D sensor alongside visual markers. This ‘interaction capture’ allows the scene to be described in terms of the spatial relationships between the character and the object using novel topological representations such as the Electric Parameters, which parametrise the outer space of an object using properties of the surface of the object. I describe the properties of these representations for motion generalisation and discuss how they can be applied to the problems of human-like motion generation and programming by demonstration. These generalised interactions are shown to be valid by demonstration of retargeting grasping and manipulation to robots with dissimilar kinematics and morphology using only local, gradient-based planning.

Micro-robotic systems are used in various fields of science and technology for the manipulation of objects of size less than a millimeter. Magnetic tweezers can be considered as micro-robotic systems due to their ability to manipulate samples of size in the range of few micrometers. In magnetic tweezers, a magnetic microparticle is manipulated by applying magnetic fields near the particle. Magnetic tweezers are popular for manipulating biological samples due to their high specificity, bio-compatibility and having an untethered end effector that enables them to manipulate inside the samples. Despite these benefits, magnetic tweezers suffer from limitations such as non-linearity in actuation, poor actuation bandwidth, the measurement strategy demanding the particle to be clearly visible and finally, the necessity of sophisticated control strategies for controlling the position of magnetic particles. This thesis investigates the design and development of a micro-robotic system with force sensing capability that addresses the actuation, measurement and control limitations of magnetic tweezers system. In order to address the actuation and measurement limitations of the magnetic tweezers, a current carrying micro-actuator is proposed to apply magnetic forces to the magnetic particles while an integrated force sensor measures the applied force. A simple analytical model for the force of interaction between the micro-actuator and magnetic particle is proposed and employed to show that force is proportional to the actuation current and position of the magnetic particle in three-dimensions (3-D). Further, simple models for mechanical stiffness and rise in temperature due to ohmic heating of the micro-actuator with force sensing capability are proposed. Subsequently, systematic guidelines are proposed for the design of the micro-actuator with force sensing capability. The designed micro-actuator with force sensing capability is fabricated and evaluated. The micro-actuator has an electrical bandwidth of about 1 MHz. The ability of the micro-actuator to apply 3-D forces to a magnetic particle is demonstrated by actuating permanent-magnet microparticles attached to micro-cantilever beams. The force sensing capability of micro-actuator is demonstrated by measuring the deflection of the micro-actuator while it is actuating a permanent-magnet microparticle. The applicability of the micro-actuator with force sensing capability is shown by employing it for the development of a magnetometer to estimate the magnetic moment of micrometer-scale magnetic particles in 3-D. The developed magnetometer is evaluated by measuring magnetic moments of both hard and soft ferromagnetic particles and untethered magnetic particles. The measured magnetic moments agree well with their theoretical counterpart with an average error of 18%. Finally, an open loop control strategy is proposed for controlling the position of magnetic particles in 2-D and 3-D respectively by applying appropriate actuation currents to the micro-actuator. Also, the force sensing capability is utilized to estimate the position of the magnetic particle along the out-of-plane axis of the micro-actuator. The estimated position of the magnetic particle is used to develop a novel scanning probe microscope (SPM) with an untethered probe. The motion of the magnetic particle in 3-D due to actuation current to the micro-actuator is estimated numerically and analyzed by using Mathieu’s equation with Dehmelt’s approximation. The control of the position of magnetic particle is demonstrated by moving the magnetic particles in pre-defined trajectories along 2-D and 3-D respectively. Further, a new strategy is developed to push samples of dimensions much smaller than the size of the magnetic particle. Finally, the imaging capability of the developed SPM is shown by imaging artificially generated topographies using a tethered probe.

There is an urgent need to develop practical and effective systems to detect diseases, such as cancer, infectious diseases and cardiovascular diseases.

Nanotechnology is a new, maturing field that employs specialized techniques to detect and diagnose infectious diseases. To this end, there have been a wealth of techniques that have shown promising results, with fluorescence and surface-enhanced Raman scattering being two important optical modalities that are utilized extensively. The progress in this specialized niche is staggering and many research groups in academia, as well as governmental and corporate organizations, are avidly pursuing leads which have demonstrated optimistic results.

Although much fundamental science is still in the pipeline under the guise of both ex-vivo and in-vivo testing, it is ultimately necessary to develop diagnostic devices that are able to impact the greatest number of people possible, in a given population. Such systems make state-of-the-art technology platforms accessible to a large population pool. The development of such technologies provide opportunities for better screening of at-risk patients, more efficient monitoring of disease treatment and tighter surveillance of recurrence. These technologies are also intrinsically low cost, facilitating the large scale screening for disease prevention.

Fluorescence has long been established as the optical transduction method of choice, because of its wealth of available dyes, simple optical system, and long heritage from pathology. The intrinsic limitations of this technique, however, have given rise to a complementary, and more recent, modality: surface-enhanced Raman scattering (SERS). There has been an explosive interest in this technique for the wealth of information it provides without compromising its narrow spectral width.

A number of novel studies and advances are successively presented throughout this study, which culminate to an advanced SERS-based platform in the last chapter.

The finite element method algorithm is critically evaluated against analytical solutions as a potential tool for the numerical modeling of complex, three-dimensional nanostructured geometries. When compared to both the multipole expansion for plane wave excitation, and the Mie-theory with dipole excitation, this algorithm proves to provide more spatially and spectrally accurate results than its alternative, the finite-difference time domain algorithm.

Extensive studies, both experimental and numerical, on the gold nanostar and Nanowave substrate for determining their potential as SERS substrates, constituted the second part of this thesis. The tuning of the gold nanostar geometry and plasmon band to optimize its SERS properties were demonstrated, and significant 3-D modeling was performed on this exotic shape to correlate its geometry to the solution's exhibited plasmon band peak position and large FWHM. The Nanowave substrate was experimentally revived and its periodic array of E-field hotspots, which was until recently only inferred, was finally demonstrated via complex modeling.

Novel gold- and silver- coated magnetic nanoparticles were synthesized after extensive tinkering of the experimental conditions. These plasmonics-active magnetic nanoparticles were small and displayed high stability, were easy to synthesize, exhibited a homogeneous distribution, and were easily functionalizable with Raman dye or thiolated molecules.

Finally, bowtie-shaped cobalt micromagnets were designed, modeled and fabricated to allow the controllable and reproducible concentrating of plasmonics-active magnetic nanoparticles. The external application of an oscillating magnetic field was accompanied by a cycling of the detected SERS signal as the nanoparticles were concentrated and re-dispersed in the laser focal spot. This constituted the first demonstration of magnetic-field modulated SERS; its simplicity of design, fabrication and operation opens doors for its integration into diagnostic devices, such as a digital microfluidic platform, which is another novel concept that is touched upon as the final section of this thesis.

Abstract Nuclear magnetic resonance is probably the most used analytical technique in chemistry and biology. It is concerned with the manipulation, by the application of magnetic fields, of the magnetic dipole moment associated with the nucleus of a particular type of atom within the molecule studied. The nuclear magnetic dipole moment may be thought of as due to a microscopic electric current loop created by a charged nucleus that has angular momentum and therefore spins. There is no exact classical analogue of the angular momentum associated with the quantum mechanical concept of spin, so that we will first predict the behaviour of the angular momentum and magnetic dipole moment associated with a single charged particle circulating in a loop, and later point out any differences between this classical orbital angular momentum and that created by a quantum mechanical spin.

This chapter focuses on the specific physical properties at domain walls in ferroelectric materials where the spontaneous electric polarization appears as a by-product of a structural or magnetic phase transition, and not as its primary order parameter. The chapter begins with a short introduction to the fundamentals of improper ferroelectricity, followed by a discussion of emergent functional domain wall properties in different improper ferroelectric model systems. It then covers the broad variety of electronic states and application opportunities associated with improper ferroelectric domain walls in hexagonal manganites. Next, this chapter addresses the electronic transport and manipulation of domain walls in boracites, and presents additional magnetoelectric coupling phenomena that arise when the interaction of magnetic spins and electric charges gives rise to improper ferroelectricity. A perspective regarding future research and application opportunities of improper ferroelectric domain walls is given last.

Annotation:

Optical isolation is important for protecting a laser from damage due to the detrimental back reflection of light. It typically relies on breaking Lorentz reciprocity and normally is achieved via the Faraday magneto-optical effect, requiring a strong external magnetic field. Single-photon isolation, the quantum counterpart of optical isolation, is the key functional component in quantum information processing, but its realization is challenging. In this chapter, we present all-optical schemes for isolating the backscattering from single photons. In the first scheme, we show the single-photon isolation can be realized by using a chiral quantum optical system, in which a quantum emitter asymmetrically couples to nanowaveguide modes or whispering-gallery modes with high optical chirality. Secondly, we propose a chiral optical Kerr nonlinearity to bypass the so-called dynamical reciprocity in nonlinear optics and then achieve room-temperature photon isolation with low insertion loss. The concepts we present may pave the way for quantum information processing in an unconventional way.

Abstract The Cretaceous Period was a time of considerable geological activity associated primarily with the disintegration of Pangaea and a considerable increase in volcanism, which had significant biogeographic consequences. As in previous chapters attention will be directed initially to the framework of major geological events before considering organic distributions. The most up-to-date plate tectonic reconstructions for the Cretaceous are those of Scotese et al. (1988), which have utilized an interactive computer graphics method. The three dimensional capabilities of this method allow the rotation and manipulation of plate outlines in ‘real time’. Two major phases of plate reorganization are recognized, in the Mid Cretaceous (95 Ma) and latest Cretaceous (65 Ma). The synchroneity of these phases across the world indicates that plate motions are interconnected and suggests to the authors that the reorganizations are triggered by the subduction of major ridge systems, or by the elimination of subduction zones due to continental collision. Furthermore the implication is that ‘slab pull’ is the dominant plate-tectonic mechanism, with oceanic spreading centres passively following lines of stress emanating from ocean trenches. Fig. 8.1 gives Scotese et al.’s global reconstruction for the Late Cretaceous, indicating the areas of new ocean floor. During the Mid Cretaceous, starting in the earliest Aptian, volcanic eruptions on a massive scale took place, registering an extraordinary upwelling of heat and deep-mantle material. Basalts were initially erupted beneath the Pacific basin and created most of the oceanic plateaus of the present-day western Pacific (Winterer 1991). Eruptions from these mantle upwellings spread to other oceans and sea-floor spreading rates increased. The overall effect was to increase the Earth’s ocean crust production by 50-100 per cent during the time interval 125 to 80 Ma. Since this time substantially coincides with a long episode of constant normal geomagnetic polarity (the so-called Quiet Zone of the ocean floor) Larsen (1991) has proposed a superplume model whereby the removal of large quantities of heat and deep-mantle material stopped the reversal process of the Earth’s magnetic field.

Annotation:

There are several techniques available to inspect single wall carbon steel pipelines including; Magnetic flux leakage (MFL), ultrasonic testing (UT), Electro-Magnetic Acoustic Transducer (EMAT), Phased Array, guide wave testing (GWT), etc. However, for more complex structures such as flexible pipelines the technology available to inspect them is far more limited. PRCI commissioned a program (SPIM 2-1) under the Subsea TC (2017-2020) to evaluate all known and suspected technologies that could be used to provide a detailed subsea inspection of a flexible riser. PRCI produced four samples of flexible pipe containing pre-manufactured cracks and corrosion defects which were located in; the outer armour layer, inner armour layer, pressure vault and carcass. The samples were used for blind testing of all identified inspection technologies. On conclusion of the SPIM 2-1 program, HR-XCT was identified as the technology showing the most promise and a follow-on program (SPIM 2-2) was commissioned to further explore the capabilities. This report will show the way in which high resolution image clarity and image manipulation was extracted from the HR-XCT system when used on the PRCI flexible pipe samples. The XCT results from SPIM 2-2 will be presented to show the initial setup of the experiment and 2D and 3D high resolution sectioned images from the testing. These images clearly identify and characterize 100% of the pre-manufactured defects introduced into the samples in all layers.
