This book discusses advanced nano-optics, from proof of concepts to real applications in devices and miniaturized instrumentation. It covers various themes and topics within nanochemistry and physics that produce enhanced optical and smart responsive materials. Development of Advanced Nano-Optics is about the development of nano-optics with advanced nanochemistry control in order to adjust physical phenomena towards new advanced and enhanced properties and related applications. It explores the development of various physical phenomena, such as the generation of high-frequency electromagnetic fields in the near field show, that have an effect in the far field. The author discusses nano-optoelectronics, light scattering nano-optics, quantum nano-optics, and advances in nanospectroscopy. He also presents proof of concepts from nanochemistry and nano-optics towards advanced applications in nanotechnology and the life sciences. Nano-optical materials in microdevices and miniaturized instrumentation are also presented and discussed. This book is written for a wide range of readers, from undergraduate students to advanced researchers, academics, and practising engineers in industry working in the fields of optics, miniaturized instrumentation, and materials.
