The concept behind this book is to provide a detailed and practical overview of the development and use of immunoassays in many different areas. Immunoassays are analytical tests that utilise antibodies to measure the amount, activity or identity of an analyte. This book is designed to provide a critical and helpful insight into the subject and to give the user practical information that may be of assistance in assay format selection, antibody generation/selection and choice of appropriate detection strategies. It is comprised of 13 chapters written by highly experienced researchers in the fields of antibody-based research, immunoassay development, assay validation, diagnostics and microfluidics. Beginning with a comprehensive survey of antibodies, immunoassay formats and signalling systems, the book elucidates key topics related to the development of an ideal antibody-based sensor, focuses on the important topic of surface modification, explores key parameters in the immobilisation of antibodies onto solid surfaces, discusses the move to ‘lab-on-a-chip’-based devices and investigates the key parameters necessary for their development. Three of the chapters are dedicated to the areas of clinical diagnostics, infectious disease monitoring and food security, where immunoassay-based applications have become highly valuable tools. The future of immunoassays, including next-generation immunoassays, electrochemical-immunoassays and ‘lab-on-a-chip’-based systems, is also discussed. The book also covers the use of optical detection systems (with a focus on surface plasmon resonance) in immunoassays, provides a compilation of important, routinely used immunoassay protocols and addresses problems that may be encountered during assay development.

Above all, it is designed to be helpful in learning more about these topics, as well as to encourage an interest in sampling and sample preparation by outlining the present practice of the technology and by indicating research opportunities. Sampling and Sample preparation is a large and well-defined field in Analytical Chemistry, relevant for many application areas such as medicine, environmental science, biochemistry, pharmacology, geology, and food science. This work covers all these aspects and will be extremely useful to researchers and students, who can use it as a starting point to design and implement their experiments and for quality-reviewed background information There are limited resources that Educators can use to effectively teach the fundamental aspects of modern sample preparation technology. Comprehensive Sampling and Sample Preparation addresses this need, but focuses on the common principles of new developments in extraction technologies rather than the differences between techniques thus facilitating a more thorough understanding Provides a complete overview of the field. Not only will help to save time, it will also help to make correct assessments and avoid costly mistakes in sampling in the process Sample and sample preparation are integral parts of the analytical process but are often less considered and sometimes even completely disregarded in the available literature. To fill this gap, leading scientists have contributed 130 chapters, organized in 4 volumes, covering all modern aspects of sampling and liquid, solid phase and membrane extractions, as well as the challenges associated with different types of matrices in relevant application areas
The basis of all immunoassays is the interaction of antibodies with antigens. The most widely used immunoassay technique is radioimmunoassay (RIA) which was first developed by Yalow and Berson in 1959. The principle of RIA is elegantly simple. It utilizes a competitve binding reaction between analytes and a radio-labeled analog of the analytes (the tracer) for anti-analyte antibodies. In addition to its exquisite specificity, extraordinary sensitivity, good accuracy and precision, ease and rapidity of assay and simplicity of assay development, the applicability of RIA to a wide variety of substances has made it one of the most powerful and versatile analytical methods of the 20th century and beyond. Millions of RIA's are being performed annually on clinical, biological and environmental samples in licensed laboratories. In order to expand the use of RIA beyond the confines of these laboratories to areas like physician's offices, patients' homes, economically less developed countries, agricultural fields, large scale and continuing screening tests for infectious diseases, it has become necessary to develop non-isotopic labels. Indeed the last fifteen years have seen the development of a great number of ingenious non-isotopic labels in immunoassay so that a whole new industry capitalizing on the potential market for non isotopic immunoassays has appeared. It is the purpose of this volume to present in depth, state-of-the-art reviews on techniques used in non-isotopic immunoassays. Topics covered include: (1) Enzyme-labeled immunoassay; (2) Luminescene immunoassay; (3) Immunoassay at liquid-solid interface; (4) Membrane immunoassay and (5) "Particle"-mediated immunoassay.
In the last three decades. use of antibiotics/drugs in animal husbandry programs has grown tremendously. Antibiotics/drugs are used therapeutically to cure diseases. and subtherapeutically to control the outbreak of diseases, improve feed efficiency and promote growth. The presence of antibiotic/drug residues in food products of animal origin. i.e •• meat, poultry and milk, can be a potential health hazard to consumers. Significant research is being done to develop new methods or to improve on existing methods to confirm and quantitatively determine the antibiotic/drug residues in meat, poultry and milk. This book covers recent development and application of various analytical techniques for the determination of antibiotic/drug residues in food products of animal origin.
