The use of nanomaterials opened new perspectives also in analytical chemistry. Despite significant advances in instrumentation, sample preparation remained a bottleneck. The special features of nanomaterials such as ultra-small size and huge surface-to-volume ratio could recently be successfully implemented in sample preparation procedures. This monograph gives a comprehensive overview of these developments: From special properties of nanomaterials over physico-chemical background up to most recent and representative applications (e.g. membranes, lab-on-a-chip echnology, and SERS), all important aspects are covered. Additionl chapters on toxicity, legal and environmental aspects make this book an unique reference.weiterlesen
