Nanotechnology is at the forefront of many of the latest developments across science and technology, but to generate and deploy these applications, macroscopic levels of nanoscale materials have to be carefully generated whilst remaining cost effective. These materials need to be reliable, consistent, and safe, and as a general principle, industries should consider green sustainable methods in the synthesis of these material and their applications as well. This book introduces readers to the field of green nanotechnologies and their possible applications to create a safer world. This accessible and practical guide will be a useful resource for material scientists, engineers, chemists, biotechnologists, and scientists working in the space of nanomaterials, in addition to graduate students in physics, chemistry, biomedical sciences and engineering.
