Combining nanotechnology, electrochemistry and biological science together, innovative bio-sensors can be delivered with the advantages of small size, high sensitivity, rapid detection and low cost. This book covers the complete information from the template-synthesis of nanoscaled materials, to the fabrication of biosensors using those nanoscaled materials, and to the fast and sensitive electrochemical detections. Attention is then given to the theoretical analysis of the interaction between the nano-structured materials and the sensing agents using electrochemical and other characterization methods. Each chapter begins with an introduction and ends with a conclusion highlighting the key points. In addition, references at the end of the chapter help you expand your research on any individual topic. In summary, this book provides useful interdisciplinary information on the design, production and application of nano- structured electrochemical biosensors.
