With nanomaterials offering new possibilities in almost every natural science, analytical chemistry is also benefiting from this development. For example, trace analysis is always difficult to achieve, due to the amount of analyte present in the sample. Nanomaterials offer a new approach to this challenging task, nicely complementing the more traditional ways of analyzing samples.

Presenting a wide variety of methods, this book provides a comprehensive overview of the current state – ranging from bioanalysis to electrochemical sensing, forensics and chemistry, while also covering the toxicity aspects of nanomaterials to humans and the environment.

For analytical chemists, materials scientists, chemists working in trace analysis, and spectroscopists.
