Conclusions and Outlook
Abstract The development of NW-based materials has led to breakthrough achievements with rapid expanding impact in all areas of nanotechnology, including but not limited to, electronics, optoelectronics, energy science, sensors and the life sciences. In spite of the progresses discussed in this book, substantial room still exists for NW research and development, and the opportunities may be realized by exquisite control of NW synthesis and assembly, as well as large scale production. In this chapter, we will summarize the basic NW research and applications introduced in this book, and challenges and exciting future opportunities will be discussed.
Central to the vision underlying nanotechnology is the idea that developing and following a common intellectual path—the bottom-up paradigm of nanoscale science and technology—will make it possible to build or assemble virtually any kind of device or functional system, ranging from ultrasensitive medical sensors to nanocomputers and brain-machine interfaces. Underpinning this bottom-up paradigm is the controlled growth of nanoscale materials—the building blocks of the bottom-up approach—pursued within the disciplines of materials sciences and chemistry. In this book we have reviewed the remarkable progress made over the past two plus decades in NW research developing this broad vision. The intimate integration and interplay between growth and fundamental characterization has enabled the field not only to expand the basic understanding of NW science and technology, but also to make rational predictions and define new device concepts unique to these nanoscale building blocks. A key that has been and will continue to be critical to continued scientific advances is expanding the level of rational synthetic control of the powerful NW building blocks with precisely controlled and tunable chemical composition, structure, size, and morphology since these characteristics ultimately determine physical properties. Moreover, the capability to create new NW topologies and assemblies where composition and structure are tuned on multiple length scales has been and will continue to be central to scientific breakthroughs, such as the first demonstrations of intracellular transistors merging key elements of living and nonliving information processors [1–3], that can enable new and potentially transformative future technologies.

Conclusions and Outlook
regard, semiconductor NWs serve as one of the most powerful platform available today in nanoscience given that it is now possible to design structures ab initio, and synthetically realize these structures with the structure and composition controlled from the atomic scale and up. This capability to design and synthetically realize complex NW materials is almost unique among nanomaterials, and enables systems or building blocks to be created, which have predi
