This book provides an understanding of emerging methods for the synthesis of nanomaterials and how they can be translated into new green approaches to manufacturing. Starting with an introduction to the principles of green chemistry and engineering, the text highlights the special properties that nanomaterials possess, their applications, and ways to characterise them. It then describes conventional methods of synthesising and manufacturing inorganic nanomaterials and introduces biological and biomimetic/bioinspired synthetic methods as a more effective and sustainable manufacturing route. Two case studies of magnetic and silica materials are also provided for advanced readers. Green Nanomaterials is an insightful reference text for researchers in the field of synthetic biology and nanomaterials. It is an essential title for postgraduates and final-year undergraduates studying advanced materials, sustainable engineering or environmental chemistry.
