firm theoretical basis for the operation of electrochemical and photoelectrochemical nanosystems. These electrochemical methods of surface characterization are extremely promising but have not received the attention already afforded spectroscopy and nuclear magnetic resonance. Allen J. Bard, noted scientist and leading researcher in the field, begins by discussing and providing numerous examples of actual integrated chemical systems - many of which are taken directly from Professor Bard's own research - and making analogies between man-made systems and those found in nature. Next, Bard moves on to an elementary general treatment of the methods available for the construction and characterization of such systems, followed by a detailed discussion of modified electrodes and electrochemical methods for characterizing them. A full chapter is devoted to semiconductor materials - which may be key components in many systems - and their use in photoelectrochemical systems. Thefinal chapter is devoted to the future of nanotechnology and promising areas for researchers to stake their claims. For university researchers and students in chemistry, physics, electrical engineering, and materials science, this book provides an elegant introduction to a
