Environmental Analysis By Electrochemical Sensors And Biosensors

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.

This book broadly reviews the modem techniques and significant applications of chemical sensors and biosensors. Chapters are written by experts in the field – including Professor Joseph Wang, the most cited scientist in the world and renowned expert on sensor science who is also co-editor. Each chapter provides technical details beyond the level found in typical journal articles, and explores the application of chemical sensors and biosensors to a significant problem in biomedical science, also providing a prospectus for the future. This book compiles the expert knowledge of many specialists in the construction and use of chemical sensors and biosensors including nitric oxide sensors, glucose sensors, DNA sensors, hydrogen sulfide sensors, oxygen sensors, superoxide sensors, immuno sensors, lab on chip, implatable microsensors, et al. Emphasis is laid on practical problems, ranging from chemical application to biomedical monitoring and from in vitro to in vivo, from single cell to animal to human measurement. This provides the unique opportunity of exchanging and combining the expertise of otherwise apparently unrelated disciplines of chemistry, biological engineering, and electronic engineering, medical, physiological. Provides user-oriented guidelines for the proper choice and application of new chemical sensors and biosensors Details new methodological advancements related to and correlated with the measurement of interested species in biomedical samples Contains many case studies to illustrate the range of application and importance of the chemical sensors and biosensors

Electrochemical Biosensors summarizes fundamentals and trends in electrochemical biosensing. It introduces readers to the principles of transducing biological information to measurable electrical signals to identify and quantify organic and inorganic substances in samples. The complexity of devices related to biological matrices makes this challenging, but this measurement and analysis are critically valuable in biotechnology and medicine. Electrochemical biosensors combine the sensitivity of electroanalytical methods with the inherent bioselectivity of the biological component. Some of these sensor devices have reached the commercial stage and are routinely used in clinical, environmental, industrial and agricultural applications. Describes several electrochemical methods used as detection techniques with biosensors Discusses different modifiers, including nanomaterials, for preparing suitable pathways for immobilizing biomaterials at the sensor Explains various types of signal monitoring, along with several recognition systems, including antibodies/antigens, DNA-based biosensors, aptamers (protein-based), and more

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.

This book is a collection of contributions from leading specialists on the topic of biosensors for health, environment and biosecurity. It is divided into three sections with headings of current trends and developments; materials design and developments; and detection and monitoring. In the section on current trends and developments, topics such as biosensor applications for environmental and water monitoring, agro-industry applications, and trends in the detection of nerve agents and pesticides are discussed. The section on materials design and developments deals with topics on new materials for biosensor construction, polymer-based microsystems, silicon and silicon-related surfaces for biosensor applications, including hybrid film biosensor systems. Finally, in the detection and monitoring section, the specific topics covered deal with enzyme-based biosensors for phenol detection, ultra-sensitive fluorescence sensors, the determination of biochemical oxygen demand, and sensors for pharmaceutical and environmental analysis.
