This book concentrates on the various fields related to the development of a nanobiosensor and presents the latest information from renowned experts. It focuses on the enhanced spectroscopy, including SERS, SEIRA/SEIRS, and near-field optics, and the related physical processes (optical properties of metallic nanoparticles, plasmon resonance, field enhancement, etc.). Some applications in the biological and medical field are presented to show the potential of such techniques as sensors if combined with functionalization.

During the last few years, nanomaterials have attracted the attention of the scientific community due to their extraordinary and unique properties. Their small size, and the distinctive features that come with it, makes these materials very attractive for use in different important fields like biomedicine, sensors, or catalysis. One of the most important properties of these materials is their interaction with light and is called surface plasmon resonance. It is a phenomenon that happens on the surface of certain nanomaterials that confers them with unique properties. This remarkable characteristic has opened a whole new field called nanoplasmonics that is acquiring more and more importance among the scientific community. This book aims to review the state of the art in this new field and provide the reader with a wide overview of the new nanomaterials available and their current and future applications.

"Alberto Diaspro has been choreographing light's dance for over 20 years, and in Nanoscopy and Multidimensional Optical Fluorescence Microscopy, he has assembled a diverse group of experts to explain the methods they use to coax light to reveal biology's secrets."- From the Foreword by Daniel Evanko, editor, Nature Methods Nanoscopy and Multidimens

The terahertz regime of the electromagnetic spectrum was largely unexplored due to the lack of technology needed to generate and detect the radiation. However, in the last couple of decades, there has been a dramatic increase in tools needed to harness the radiation. This remarkable progress made in the development of terahertz sources, components, and detectors has resulted in an ever-increasing inquisitiveness of the applications of terahertz technology in a wide range of fields including medicine, pharmaceuticals, security, sensing, and quality assurance. This book, Terahertz Spectroscopy - A Cutting Edge Technology, presents an overview of the recent advances in terahertz technology and their application in a vast array of fields. The scientists and students are encouraged to read and share the content of this volume. The book also provides a good starting point for researchers who are new to the terahertz regime. The various chapters of the book have been written by renowned scientists in different parts of the world who are at the forefront of terahertz research fields. It is our (InTech publisher, editor, and authors) hope that this book will enhance knowledge and stimulate more interest and future research in terahertz technology.

Plasmonics is entering the curriculum of many universities, either as a stand alone subject, or as part of some course or courses. Nanotechnology institutes have been, and are being, established in universities, in which plasmonics is a significant topic of research. Modern Plasmonics offers a comprehensive presentation of the properties of surface plasmon polaritons, in systems of different structures and various natures, e.g. active, nonlinear, graded, theoretical/computational and experimental techniques for studying them, and their use in a variety of applications. Contains material not found in existing books on plasmonics, including basic properties of these surface waves, theoretical/computational and experimental approaches, and new applications of them Each chapter is written by an expert in the subject to which it is devoted Emphasis on applications of plasmonics that have been realized, not just predicted or proposed

This book focuses on recent interconnected topics in nanophotonics written by scientists at the forefront of these fields. The book presents results of numerical investigations of light-matter interactions at the nanoscale and in the attosecond regime using first-principles calculations while also discussing recent experimental developments of higher-order harmonic generation for the field of attosecond science. In addition to this, the book reviews recent advances in select topical areas such as highly efficiency solid-state light sources based on nanophotonics, plasmonic photochemical water splitting for efficient energy harvesting, and optical spectroscopy of single-walled carbon nanotubes with quite rich physics for future application in photonics.

Nanoplasmonics is a young topic of research, which is part of nanophotonics and nano-optics. Nanoplasmonics concerns to the investigation of electron oscillations in metallic nanostructures and nanoparticles. Surface plasmons have optical properties, which are very interesting. For instance, surface plasmons have the unique capacity to confine light at the nanoscale. Moreover, surface plasmons are very sensitive to the surrounding medium and the properties of the materials on which they propagate. In addition to the above, the surface plasmon resonances can be controlled by adjusting the size, shape, periodicity, and materials' nature. All these optical properties can enable a great number of applications, such as biosensors, optical modulators, photodetectors, and photovoltaic devices. This book is intended for a broad audience and provides an overview of some of the fundamental knowledges and applications of nanoplasmonics.
