Nanomaterials contain some unique properties compared to their bulk. Their unique properties are due to the chemical nature of the material, small size, and surface functionalization. Along with control over size, the functionalization of nanomaterials also affects their compatibility to the environment and living organisms. This book provides a detailed account of nanomaterials functionalization along with a brief overview of their application.This book serves as a reference for scientific investigators including doctoral and postdoctoral scholars and undergradate and graduate students who need to have knowledge of the basics of nanomaterial functionalization, recent advancements, challenges, and opportunities in this field. This book will also provide critical and comparative data for nano-technologists and may be beneficial for industry personnel, journalists, policy makers, and the general public to help understand functionalized nanomaterials in detail and in depth. Features: This book is comprehensive and covers all aspects of functionalized nanotechnology. It describes the challenges and methods of functionalized nanomaterials synthesis for different applications. It discusses the recent findings and cutting-edge global research trends on the functionalization of nanomaterials. It emphasizes the products and market, safety, and regulatory issues of functionalized nanomaterials.
