ABSTRACT
This chapter provides an exhaustive review of state-of-the-art research into green nanomaterials synthesis, their custom-tailored structure-based properties and the associated applications in optoelectronics, semiconductors, biomedical, therapy, pharmaceutical and water treatment. The scope of properties and applications of green nanomaterials, is thus, tremendous. The chapter focuses on specific areas of research and development of the green production of nanomaterials, some of their more preferred structure-based properties and the associated applications in disparate disciplines. It elaborates on the structure-based useful properties of nanomaterials, where the fundamental forces of nature and physical theories have very different outcomes compared to the macroscopic world. The chapter discusses the multidisciplinary applications of green nanomaterials, especially in optoelectronics and spectroscopy. The extant research literature abounds with reports of research investigating the plant-based synthesis of green nanomaterials, nanostructures and nanocomposites. The negative consequences of run-away industrialization, accumulation of wastes and the need for environmental remediation have sparked the growth in green nanomaterials research.
