A primary text for undergraduate nanotechnology courses, this book is designed for students who lack a cross-disciplinary background and knowledge of micro- and nano-technology. It contains examples, questions, and problems divided into three hierarchical learning skills: understanding, analyzing, and evaluating the concepts. The author breaks down the boundaries between biology, chemistry, physics, engineering and ethics by co-mingling the vocabularies and concepts of these disciplines around bio-applications. Copiously illustrated, this text emphasizes biological and biomedical applications and includes a comprehensive chapter on ethics. Ancillaries are available with qualifying course adoption.
