Photonic crystals, since their discovery in 1987 have been of great interest to the optics community. Their unique optical properties have revolutionized the field of photonics and have enabled a new class of optical devices with applications in a broad range of areas such as creating nanophotonic light guiding circuits, efficient optical add-drop filters and modulators as well as a new class of low loss optical fibers. This thesis work aims to exploit the optical properties of photonic crystals that enable them to strongly confine and guide light towards developing and designing novel optical devices for performing optofluidic transport, trapping and biosensing. While optical biosensors are of great interest to the biosensing community, one of the limitations of current optical nanobiosensors is their inability to perform a large number of detections in parallel. I have demonstrated a novel one-dimensional resonant photonic crystal architecture that is extremely well suited for performing highly sensitive and multiplexed, label-free biological detections. These sensors also have very a small form-factor allowing for the successful detection of tens of attograms of bound mass on the sensor surface. Over the last two decades, optical tweezers have been developed to exert optical forces for trapping and manipulating microparticles and cells. However, they exhibit two significant drawbacks. Firstly, they have a very small interaction length over which they can exert optical forces on particles thus limiting the distances over which particles can be propelled using optical scattering forces. Additionally, they are diffraction limited systems which make them incapable of trapping smaller objects such as dielectric nanoparticles and biomolecules. In my doctoral work, I have demonstrated for the first time, the ability to exploit liquid-core waveguiding structures to propel dielectric microspheres over long distances due to their ability to strongly confine and guide light thus overcoming the limitation of previous systems with respect to their small interaction lengths. I have also demonstrated a resonant photonic crystal architecture that overcomes the limitations imposed by diffraction by confining the optical field to sub-wavelength volumes while simultaneously amplifying it. This has enabled the trapping of nanoparticles as small as 48-nm (in diameter) and trap stiffnesses that are an order of magnitude higher than the current state-of-the-art. The results of this work will enable future devices with the ability to potentially trap and sense single biomolecules such as proteins. In addition, by integrating these photonic crystal elements with other photonic circuit elements, it opens up a vast number of exciting possibilities for optofluidically enabled transport in micro and nano-fluidic systems. In particular, my doctoral research lays down the groundwork for enabling future work on sensitive size based optical chromatography and ultra-sensitive biosensors.

Nanosized sensors enable the study of chemical and biochemical processes at a level and in dimensions that may not have been envisioned some 20 years ago. Fueled by their inherent small size and the unusual optical, magnetic, catalytic, and mechanical properties of nanoparticles, remarkable progress has been made in recent years in the development and utilization of nanosensors and optical nanotechnology will further widen the field. However, the design of new sensors requires new materials, new methods for their characterization, new optical sensing schemes, new approaches for creating nanosized structures, and new techniques for their interrogation in complex environments such as small living cells for studying biological signals or big public spaces for environmental monitoring . Optochemical Nanosensors covers the rapidly growing field of optical chemical nanosensing, a new and exciting area of research and development within the large field of optical chemical sensing and biosensing. Its many applications, including the detection of bioterrorist threats, food security, virology, explosive detection and more, are covered in these self-contained yet interrelated chapters. The book reviews optochemical sensors, starting from the basics in optoelectronicsand concluding with the presentation of diverse nanosensors. The authors offer insight into future trends in this growing field and present applications in the fields of medicine, security, and bioterrorism.

The most comprehensive reference on fluorescent nanodiamond physical and chemical properties and contemporary applications Fluorescent nanodiamonds (FNDs) have drawn a great deal of attention over the past several years, and their applications and development potential are proving to be manifold and vast. The first and only book of its kind, Fluorescent Nanodiamonds is a comprehensive guide to the basic science and technical information needed to fully understand the fundamentals of FNDs and their potential applications across an array of domains. In demonstrating the importance of FNDs in biological applications, the authors bring together all relevant chemistry, physics, materials science and biology. Nanodiamonds are produced by powerful cataclysmic events such as explosions, volcanic eruptions and meteorite impacts. They also can be created in the lab by high-pressure high-temperature treatment of graphite or detonating an explosive in a reactor vessel. A single imperfection can give a nanodiamond a specific, isolated color center which allows it to function as a single, trapped atom. Much smaller than the thickness of a human hair, a nanodiamond can have a huge surface area that allows it to bond with a variety of other materials. Because of their non-toxicity, nanodiamonds may be useful in biomedical applications, such as drug delivery and gene therapy. The most comprehensive reference on a topic of rapidly increasing interest among academic and industrial researchers across an array of fields Includes numerous case studies and practical examples from many areas of research and industrial applications, as well as fascinating and instructive historical perspectives Each chapter addresses, in-depth, a single integral topic including the fundamental properties, synthesis, mechanisms and functionalisation of FNDs The first book published by the key patent holder with his research group in the field of FNDs Fluorescent Nanodiamonds is an important working resource for a broad range of scientists and engineers in industry and academia. It will also be a welcome reference for instructors in chemistry, physics, materials science, biology and related fields.
