Guided by molecular and quantum theories, this contributed volume gives a broad picture of the current and past advances that were necessary to develop nano sensors using nano materials. To illustrate the important and relevant applications of nano materials, Design and Applications of Nano materials for Sensors focuses on recent advances that extend the scope of possible applications of the theory, improve the accuracy with respect to experimentation and reduce the cost of these calculations. This volumealso features new applications of theoretical chemistry methods to problems of recent general interest in nanotechnology whereby large computational experiments are now necessary.
