Nanotechnology-Based E-Noses: Fundamentals and Emerging Applications

Nanotechnology-Based E-Noses: Fundamentals and Emerging Applications reviews advances in nanomaterials and their modification for use in e-sensors. Theoretical understanding of nanomaterials and technologies for improving sensors with better detection limits are covered, as are the most relevant nanomaterials, their synthesis strategies and the relationship between properties and device performance. Current state-of-the-art progress in nanotechnology device fabrication, along with directions for future applications and challenges are also discussed. This book will be an ideal resource for materials scientists, engineers, chemists, researchers in academia and R&D in industry.

Recently, e-noses or electronic sensors are emerging as advanced technologies for the fast detection of chemicals, gases and explosives. The concept behind the e-nose is similar to the capability of humans and dogs in detecting materials based on odors. Nanomaterials can be used for e-nose technologies but their properties must be modified to make them effective sensors. The sensing capability and performance these materials depend on several factors such as morphology, dopants, micro-additives, design of sensors, phase and structure of the nanomaterials.
