Book Description
Current developments in optical technologies are being directed toward nanoscale devices with subwavelength dimensions, in which photons are manipulated on the nanoscale. Although light is clearly the fastest means to send information to and from the nanoscale, there is a fundamental incompatibility between light at the microscale and devices and processes at the nanoscale. Nanostructured metals which support surface plasmon modes can concentrate electromagnetic (EM) fields to a small fraction of a wavelength while enhancing local field strengths by several orders of magnitude. For this reason, plasmonic nanostructures can serve as optical couplers across the nano–micro interface: metal–dielectric and metal–semiconductor nanostructures can act as optical nanoantennae and enhance light matter coupling in nanoscale devices. This book describes how one can fully integrate plasmonic nanostructures into dielectric, semiconductor, and molecular photonic devices, for guiding photons across the nano–micro interface and for detecting molecules with unsurpassed sensitivity.·Nanophotonics and Nanoplasmonics·Metamaterials and negative-index materials·Plasmon-enhanced sensing and spectroscopy·Imaging and sensing on the nanoscale·Metal Optics

Book Description
This book gives a comprehensive overview of recent advancements in both theory and practical implementation of plasmonic probes. Encompassing multiple disciplines, the field of plasmonics provides a versatile and flexible platform for nanoscale sensing and imaging. Despite being a relatively young field, plasmonic probes have come a long way, with applications in chemical, biological, civil, and architectural fields as well as enabling many analytical schemes such as immunoassay, biomarkers, environmental indexing, and water quality sensing, to name but a few. The objective of the book is to present in-depth analysis of the theory and applications of novel probes based on plasmonics, with a broad selection of specially-invited chapters on the development, fabrication, functionalization, and implementation of plasmonic probes as well as their integration with current technologies and future outlook. This book is designed to cater to the needs of novice, seasoned researchers and practitioners in academia and industry, as well as medical and environmental fields.

Book Description
Plasmonic Sensors and their Applications A practically-focused reference and guide on the use of plasmonic sensing as a faster and cheaper alternative to conventional sensing platforms Plasmons, the collective oscillations of electrons occurring at the interface between any two materials, are sensitive to changes in dielectric properties near metal surfaces. Plasmonic sensors enable the real-time study of unique surface properties by monitoring the effect of the material interaction at the sensor surface. Plasmonic sensing techniques offer fast, label-free analysis, and hold advantages over labelling techniques such as ELISA (enzyme-linked immunosorbent assay). Plasmonic Sensors and their Applications examines the development and use of highly sensitive and selective plasmonic sensing platforms in chemistry, biotechnology, and medicine. Contributions by an international panel of experts provide timely and in-depth coverage of both real-world applications and academic research in the dynamic field. The authors describe advances in nanotechnology, polymer chemistry, and biomedicine, explore new and emerging applications of plasmonic sensing, discuss future trends and potential research directions, and more. This authoritative volume: Demonstrates why plasmonic sensing is a profitable method for easy and label-free analysis in real-time Covers a variety of applications of plasmonic sensors, such as disease diagnostics, vitamin detection, and detection of chemical and biological warfare agents Includes a brief introduction to the history and development of plasmonic sensors Provides concise theory and background for every application covered in the text Plasmonic Sensors and their Applications is an invaluable resource for analytical chemists, biochemists, biotechnologists, protein and surface chemists, and advanced students of biotechnology.

Book Description
Noble metal nanoparticles exhibit unique optical properties arising from the resonant oscillations of their conduction electrons with light. This phenomenon is called localized surface plasmon resonance (LSPR). The LSPR frequency is extremely sensitive to the size, shape, refractive index at the metal-dielectric interface, and other nearby metal nanoparticles. In an assembly of proximal nanoparticles, the LSPR of individual particles can couple to yield enhanced light scattering and large spectral shifts, which are useful for many applications including diagnostics and sensing. This dissertation presents a complex nanostructure comprising a core gold nanoparticle surrounded by multiple satellite gold nanoparticles for biosensing application. Chapter 2 introduces the fabrication and characterization of the core-satellite assemblies via a layer-by-layer process. Using ATP-aptamer as the linker, we demonstrated the detection of ATP based on the disassembly of the nanostructure, which can be readily captured by darkfield microscopy. The detection limit, dynamic range, and sensitivity can be tuned by controlling the size of the assembly. We found that the aptamer-linked nanoparticle assemblies were selective to only ATP, and not other adenine-containing compounds. Additionally, sensing of ATP in buffer and in bulk cell lysates was demonstrated. Chapter 3 presents the methodology for detecting ATP directly from lysed cells, down to the single-cell level without the need for purification or extraction. The intracellular ATP levels of two ovarian cancer cell lines were quantified to elucidate the differences and cellular distribution, and the potential of the stick-and-peel platform for mapping the microenvironment of 2D heterogeneous surfaces was demonstrated. In chapter 4, the optical properties of nanoparticle assemblies were tuned by changing the morphology of the nano building block, where the incorporation of gold nanoshells as satellites led to an extended redshift of LSPR to a much longer wavelength compared with using solid gold nanoparticles as satellites. This tunability in the LSPR of the assemblies allows for color-based analysis and color-coding of the plasmonic sensors. Lastly, Chapter 5 outlines the development of a multiplexed assay using the nanoparticle assemblies. Two types of assemblies, targeting either ATP or a nucleic acid (DNA-210), were fabricated with different DNA linkers in the same sensing area. The multiplexing was demonstrated by the selective disassembly process. Moreover, the ability to tune the optical properties of nanostructures using different morphologies was integrated; two different morphology of nanostructures, i.e. solid-solid and solid-shell nanostructures, for two targets, ATP and DNA-210, respectively, were fabricated. Based on a difference in scattered color, two types of biosensors among thousands of nanoparticle assemblies can be easily identified. Finally, we demonstrated duplex detection based on the change in the scattering intensity and the color read-out. Reflecting on the contributions of our work, this dissertation advances the fundamental knowledge and practical design of chip-based sensing platforms comprising complex plasmonic nanostructures. The work contributes to the sensing field by addressing some of the challenges in point-of-care or point-of-need measurement applications and provides an alternative bioanalytical tool for single-cell based analysis.

Book Description
Plasmonics is a rapidly developing field that combines fundamental research and applications ranging from areas such as physics to engineering, chemistry, biology, medicine, food sciences, and the environmental sciences. Plasmonics appeared in the 1950s with the discovery of surface plasmon polaritons. Plasmonics then went through a novel propulsion in the mid-1970s, when surface-enhanced Raman scattering was discovered. Nevertheless, it is in this last decade that a very significant explosion of plasmonics and its applications has occurred. Thus, this book provides a snapshot of the current advances in these various areas of plasmonics and its applications, such as engineering, sensing, surface-enhanced fluorescence, catalysis, and photovoltaic devices.
