Bioelectronic Nose

The “bioelectronic nose”, the device which has a similar function to the human smell sensing system, can be realized by combining the olfactory cells or receptors with nanotechnology. In the last two decades, much has been learned about the smell sensing mechanism in biological systems. With knowledge about the biological olfactory system and the techniques for the expression of biological receptor proteins, we are able to utilize biological materials and systems to mimic the biological olfactory system. In addition to the advances in biological and biotechnological area, nanotechnology has progressed to a great degree. The bioelectronic nose is a good example of the integration of biotechnology and nanotechnology. This book describes basic biological sciences of the olfactory system, biotechnology for the production of olfactory biological elements, and nanotechnology for the development of various sensing devices. The purpose of this book is to provide the reader with a concept, basic sciences, fundamental technologies, applications, and perspectives of the bioelectronic nose.

Nanotechnology-based E-Noses reviews advances in nanomaterials and their modification for use in e-sensors. "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 of these materials depend on several factors, such as morphology, dopants, microadditives, design of sensors, phase, and structure of the nanomaterials. Theoretical understanding of nanomaterials and technologies for improving sensors with better detection limits are covered. The most relevant nanomaterials, their synthesis strategies, and the relationship between properties and device performance are provided. Current state-of-the-art progress in nanotechnology device fabrication along with directions for future applications and challenges are discussed. Covers fundamentals of nanomaterials for electronic sensing applications, including material synthesis and property optimization strategies to improve material performance Reviews emerging relevant nanomaterials including 1D, 2D and 3D nanomaterials for use in e-nose technologies Discusses nanotechnology-based e-noses and their wide range of applications in the detection of chemicals, gases, explosives, and more

Water is an indispensable resource for our society. Essential to sustaining life and economic prosperity, water is also the basic component for manufacturing almost everything to keep society alive, including energy, food, clothing, cars, and electronics, among many other examples. It is, thus, an integral part of our lives beyond simply quenching our thirst. In addition, our future economy and security highly depend upon the availability of clean water. Yet given its critical importance, there is a limited supply of renewable freshwater across the globe and there is no substitute. Global population and economic growth, urbanization, and climate change further exacerbate the increasing stress on freshwater supplies. As such, society urgently needs to find the scientific and engineering solutions to more efficiently manage our precious water resources. The volumes of this multi-volume reference cover the latest scientific advancements and solutions in managing and treating this crucial resource.Related Link(s)

The Springer Handbook of Odor is the definitive guide to all aspects related to the study of smell and their impact on human life. For the first time, this handbook aligns the senso-chemo-analytical characterization of everyday smells encountered by mankind, with the elucidation of perceptual, hedonic, behavioral and physiological responses of humans to such odors. From birth onwards we learn to interact with our environment using our sense of smell. Moreover, evolutionary processes have engendered a multi-faceted communication that is supported – even dominated – by olfaction. This compilation examines the responses of humans to odors at different stages of life, thereby building a foundation for a widely overseen area of research with broader ramifications for human life. The expert international authors and editor align aspects, concepts, methodologies and perspectives from a broad range of different disciplines related to the science of smell. These include chemistry, physiology, psychology, material sciences, technology but also disciplines related to linguistics, culture, art and design. This handbook, edited by an internationally renowned aroma scientist with the support of an outstanding team of over 60 authors, is an authoritative reference for researchers in the field of odors both in academia and in industry and is also a useful reference for newcomers to the area.
