Biosensors For Environmental Diagnostics

This book reflects the current knowledge and trends in the field of biosensors for environmental monitoring. Biosensors combine the power of microelectronics with the selectivity and sensitivity of biological components to detect individual substances or groups of substances in the environment. Biosensors can also be used for recognizing biological effects such as genotoxicity, immunotoxicity and endocrine responses. For this purpose, components of biological origin such as microorganisms, enzymes, receptors or specific nucleic acid sequences are applied for the recognition and combined with a transducer system to provide toxicologic or pharmacologic data within seconds. This approach is expected not only to provide a significant contribution to measurement technology but also a basis for competent political decisions.

Electrochemical Nano-biosensors: Applications in Diagnostics, Therapeutics, Environment, and Food Management features a critical overview of different, recently reported nanomaterial-based electrochemical sensing and biosensing strategies.

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.

A biosensor is a detecting device that combines a transducer with a biologically sensitive and selective component. Biosensors can measure compounds present in the environment, chemical processes, food and human body at low cost if compared with traditional analytical techniques. This book covers a wide range of aspects and issues related to biosensor technology, bringing together researchers from 16 different countries. The book consists of 24 chapters written by 76 authors and divided in three sections: Biosensors Technology and Materials, Biosensors for Health and Biosensors for Environment and Biosecurity.
