Nanomaterials electrochemical sensors

Chapters 1 to 5 deal with ionophore-based potentiometric sensors or ion-selective electrodes (ISEs). Chapters 6 to 11 cover voltammetric sensors and biosensors and their various applications. The third section (Chapter 12) is dedicated to gas analysis. Chapters 13 to 17 deal with enzyme based sensors. Chapters 18 to 22 are dedicated to immuno-sensors and genosensors. Chapters 23 to 29 cover thick and thin film based sensors and the final section (Chapters 30 to 38) is focused on novel trends in electrochemical sensor technologies based on electronic tongues, micro and nanotechnologies, nanomaterials, etc.

Food analysis is a major application area of electrochemical sensors and biosensors. One of the key aspects driving their dramatic development in recent years has been, among others, the use of nanomaterials. As it is outlined below, nanoscience and nanotechnology has strongly influenced the design and construction of recent electrochemical sensors and biosensors paving the way for nanostructured electrode surfaces which are able to improve the quality of the electrochemical response and allowing the efficient immobilization of biomolecules. 

A wide range of newly introduced nanoscale materials is expected to expand the realm of nanomaterial-based electrochemical sensors and biosensors. In addition, the judicious coupling of two different nanomaterials (i.e., inorganic/carbon nanohybrids) has been shown to offer further improvements in the analytical performance, superior to that observed when a single nanomaterial is used [55]. Such nanobioelectronic devices are expected to have a major impact upon ensuring our food safety or water quality, and upon other areas ranging from clinical diagnostics to security surveillance. 

Electrochemical sensors, modified with nanomaterial, have contributed to create great expectations in the last decade [4-8]. New materials such as carbon nanotubes [8-10], metal [3, 5, 11-16] and polymer nanoparticles [14, 17-20], carbon nanofibers [21-23], and boron-doped diamond nanograss [24] are ideal for electrochemical sensors due to their high surface area, high aspect ratio, and enhanced catalytic properties [25-30].
