This book highlights the wide applications of nanomaterials in healthcare and environmental remediation. Presenting nano-based materials that positively influence the growth and proliferation of cells present in soft and hard tissue and are used for the regeneration bone tissue and/or suppression of cancer cells, it also discusses the natural products that can be incorporated in nanofibers for the treatment of cancer.  Further, it describes the use of blending and functionalization to produce chitosan nanofibers for biomedical applications, and reviews the role of plasma-enhanced gold nanoparticles in diagnostics and therapeutics.  Lastly, the book also introduces various nanotechnology approaches for the removal of waste metabolites in drinking water, and explores the emerging applications of nanorobotics in medicine. Given its scope, this book is a valuable resource for scientists, clinicians, engineers and researchers aiming to gain a better understanding of the various applications of nanotechnology.
