This book is a compendium of papers edited by Ahmed S. Khan, an educator and researcher at DeVry University in Addison, IL, U.S.A. DeVry University, whose presence now is mainly but not exclusively online, is a descendant of the former DeVry Technical Institute. The same kinds of technology that enable us to put billions of transistors on a single chip have led to the ability to make increasingly complex nanostructures for a wide variety of other uses, ranging from electronics to chemistry and medicine.
