Biosensors For Direct Monitoring Of Environmental Pollutants In Field

Biosensors offer clear and distinct advantages over standard analytical methods for the direct monitoring of environmental pollutants in the field, such as real-time detection with minimum sample preparation and handling. The present book highlights recent advantages that will be of great value to a range of scientists, researchers and students dealing with analytical and environmental chemistry and biosensor technology. It presents recent trends in analytical methodology for the determination of indoor and outdoor pollutants, advances in DNA, biological and recognition-based sensors, examples of biosensors for use in field and water analysis, biosensors based on non-aqueous systems, and recent advances in the miniaturisation and micromachining of biosensors.

During recent years both research activity and the number of reports on biosensor systems applied to environmental analysis have increased significantly. Compounds present in the environment have increasingly been shown to have effects on biological systems such as cells, enzymes, binding proteins, and DNA. In order to deal with the increasing demand for information about possible pollution of the environment there is need for improvements to analytical methods. Thus, biochemistry-based analytical methods should offer the possibility of monitoring these effects. This text provides an overview of existing biosensor principles, commercially available instruments, and related biochemical assays which have been developed and applied to environmental monitoring. Providing the reader with detailed information on methodology and a description of the practical application of selected sensors, this text also includes reports on established chemical methods for comparison. This volume presents fundamental principles together with examples of applications and discussion of drawbacks, and future developments. Of interest to all in the field of environmental analysis and biosensor technology, this text provides a comprehensive treatise on the latest research and developments in the field.

Real-time and reliable detection of molecular compounds and bacteria is essential in modern environmental monitoring. For rapid analyses, biosensing devices combining high selectivity of biomolecular recognition and sensitivity of modern signal-detection technologies offer a promising platform. Biosensors allow rapid on-site detection of pollutants and provide potential for better understanding of the environmental processes, including the fate and transport of contaminants.This book, including 12 chapters from 37 authors, introduces different biosensor-based technologies applied for environmental analyses.

Biosensors are poised to make a large impact in environmental, food, and biomedical applications, as they clearly offer advantages over standard analytical methods, including minimal sample preparation and handling, real-time detection, rapid detection of analytes, and the ability to be used by non-skilled personnel. Covering numerous applications of biosensors used in food and the environment, Portable Biosensing of Food Toxicants and Environmental Pollutants presents basic knowledge on biosensor technology at a postgraduate level and explores the latest advances in chemical sensor technology for researchers. By providing useful, state-of-the-art information on recent developments in biosensing devices, the book offers both newcomers and experts a roadmap to this technology. In the book, distinguished researchers from around the world show how portable and handheld nanosensors, such as dynamic DNA and protein arrays, enable rapid and accurate detection of environmental pollutants and pathogens. The book first introduces the basic principles of biosensing for newcomers to the technology. It then explains how the integration of a "receptor" can provide analytically useful information. It also describes trends in biosensing and examines how a small-sized device can have portability for the in situ determination of toxicants. The book concludes with several examples illustrating how to determine toxicants in food and environmental samples.

This book approaches the topic of environmental biotechnology in a clear, integrated, and meaningful way, covering both the fundamentals and biochemical processes involved, as well as the technologies themselves within different areas of application. As part of the framework, it also provides a thorough description of the pollution and its control, and the role of microorganisms in a wide range of ecosystems and deterioration processes. Features: Focuses on the role of microorganisms in a wide range of ecosystems and deterioration processes. Explains underlying concepts of environment, interlinks them from an ecological point of view, and describes the approaches for waste treatment. Describes the concepts and fate processes of environmental contaminants, contaminant patterns in soil, groundwater, and surface water. Includes novel research findings and applications of biosurfactants. Discusses biodegradation as a key process in the bioremediation of recalcitrant compounds. This book is aimed at Primarily Senior Undergraduates including Graduate Students and Researchers in Biotechnology, Environmental Science/Engineering, Conservation Biology, Microbiology, Waste Management, and Ecology.

This book presents an exhaustive overview of electrochemical sensors and biosensors for the analysis and monitoring of the most important analytes in the environmental field, in industry, in treatment plants and in environmental research. The chapters give the reader a comprehensive, state-of-the-art picture of the field of electrochemical sensors suitable to environmental analytes, from the theoretical principles of their design to their implementation, realization and application. The first three chapters discuss fundamentals, and the last three chapters cover the main groups of analytes of environmental interest.

Recent advances in array-based detectors and imaging technologies have provided high throughput systems that can operate within a substantially reduced timeframe and other techniques that can detect multiple contaminants at one time. These technologies are revolutionary in terms of food safety assessment in manufacturing, and will also have a significant impact on areas such as public health and food defence. This book summarizes the latest research and applications of sensor technologies for online and high throughput screening of food. The book first introduces high throughput screening strategies and technology platforms, and discusses key issues in sample collection and preparation. The subsequent chapters are then grouped into four sections: Part I reviews biorecognition techniques; Part II covers the use of optical biosensors and hyperspectral imaging in food safety assessment; Part III focuses on electrochemical and mass-based transducers; and finally Part IV deals with the application of these safety assessment technologies in specific food products, including meat and poultry, seafood, fruits and vegetables. Summarises the latest research on sensor technologies for online and high-throughput screening of food Covers high-throughput screening and the current and forecast state of rapid contaminant detection technologies Looks at the use of optical and electrochemical biosensors and hyperspectral imaging in food safety assessment and the application of these technologies in specific food products

Biosensor technology has rapidly expanded into a wide variety of applications in the last few years. This book focuses on several aspects of neural behavior both in vitro and in vivo, and for the first time, the detection of populations of neurons is presented.
