We have learnt the benefits of green synthesis, but before we can explore sustainable bioinspired green synthesis of nanomaterials, it is important to understand what nanomaterials are, and how we can use them. Nanomaterials, nanotechnology and particularly biomedical applications of nanotechnology have captured our imagination in both science and fiction for decades, even before nanotechnology was scientifically realised: the concept of nanobots, removing diseased cells from our blood stream, is a very clear image in sci-fi literature, and excitingly it is actually something that we believe will become a reality in the coming years.

This section is devoted to highlighting special properties of nanomaterials within the scope of this book, illustrating their functions and how these properties serve several emerging and well-known applications with selected examples. Given these special features, which may not be found in bulk materials, an entire chapter focuses on giving an introduction to various key characterisation techniques used for studying and measuring properties of nanomaterials. This is followed by a description of ‘top-down’ and ‘bottom-up’ current and emerging methods for nanomaterials synthesis and manufacturing along with the physicochemical principles of nanomaterial formation. Suitable examples of the chemistry of materials are provided to help illustrate the processes.
