Biosensoren vereinigen so inkompatible Welten wie Molekularbiologie und Elektronik. Das Potential für Anwendungen von Biosensoren ist enorm hoch und reicht von der Messung der Ölverschmutzung unserer Weltmeere bis zur Bestimmung des Glucosespiegels im Blut. Das vorliegende Buch gibt zunächst eine Einführung in die Molekularbiologie und Biochemie, soweit dies zum Verständnis der Biosensor-Technologie notwendig ist. Es werden dann die verschiedensten Biosensor-Typen sowie deren wissenschaftliche und kommerzielle Anwendungen beschrieben.
Biosensors combine the unique properties of biological systems to selectively recognize and convert molecules with the benefits of physicochemical sensor technology, such as high sensitivity, simplicity of operation and mass production, and modern electronics. Consequently, their development is closely related to progress in two branches of high technology - biotechnology and microelectronics. This book not only presents the state-of-the-art of biosensor research and development to the specialist, but also introduces the layman to the fundamentals of the subject. The relevant features of physicochemical transducer elements as well as biochemical recognition molecules (enzymes, antibodies, receptors) are outlined. Biochemical and biotechnological aspects of biomolecule immobilization and the interplay of biochemical reactions and mass transfer processes are comprehensively treated with regard to their impact on successful sensor design. Examples of immobilization methods are described in detail. The employment of coupled enzyme reactions, higher integrated biocatalytic systems (cell organelles, microbes, tissue sections) and immunocomponents in biosensors is covered extensively. Optical, thermometric, piezoelectric and particularly electrochemical biosensors for more than 100 analytes are presented, including immunosensors. The relative merits and limits of biosensors are discussed using several examples of their application in clinical chemistry, bioprocess control and environmental monitoring. Finally, the application of biosensors in medicine, biotechnology, food industry and environmental control is discussed, including commercialization and problems to be addressed in future research.
This introductory text covers in detail the technology and applications of biosensors in their many forms. It provides an extensive survey of the basic principles, functions and applications of different categories of biosensors. The presentation is concise, systematic and well illustrated. Numerous schematics illustrate design and function. This book is an overview of the basic theories of operation for a number of specific types of biosensor transducers that have been investigated, with a general survey of some of the many applications using various biological elements that have been tested to date. A major portion of this book has been devoted to electrochemical transducers, since they have been most widely used. This bestselling text provides basic information for all those involved in the research, development, and applications of biosensors.
Of all the recent discoveries in biotechnology, that of biosensor is one of those which has seen an exponential expansion over the last few years. This evolution corresponds with the increasing need for measuring devices that can follow continuously changing biological processes. Biosensors can meet this need provided that their signals include all the information necessary for an understanding of the process, especially concerning the nature and concentration of the species present in the sample medium. It is well known that sensors form the basis of all instrumental analysis systems, but they also represent the limiting factors of such systems. In this book, we restrict ourselves to the description and study of sensors, leaving aside the different aspects of signal and data treatment. We believe, however, that it is important to stress the multifaceted character of biosensors, and the applications and economic factors which follow. Biosensor construction is essentially based on the immobilization of a bioreceptor on the corresponding transducer. The reader will find that there are a large variety of techniques for immobilizing enzymes, cofactors and mediators, and even microorganisms, immunoagents, e now commercially available. Other types of tissues, and organelles. A large part of this book is devoted to enzyme biosensors are discussed, with regard to both the principles of their sensors, which is hardly surprising considering that they have been operation, and their construction.
The application of biosensors is expanding in different areas. These are portable and convenient devices that permit the rapid, accurate, and reliable detection of analytes of interest present either in the atmosphere or in aqueous or in liquid phases. The detection of glucose levels in blood for the effective management of diabetes is one. Though different biosensors have been designed for an increasing number of applications, the kinetics of binding (and dissociation) of analytes by the receptors on the biosensor surfaces has not been given enough attention in the open literature. This is a very important area of investigation since it significantly impacts biosensor performance parameters such as stability, sensitivity, selectivity, response time, regenerability, etc. Binding and Dissociation Kinetics for Different Biosensor Applications Using Fractals addresses this critical need besides helping to correct or demonstrate the need to modify the present software available with commercial biosensors that determines the kinetics of analyte-receptor reactions on biosensor surfaces. * first book to provide detailed kinetic analysis of the binding and dissociation reactions that are occuring on the biosensor surface * addresses the area of analyte-receptor binding and dissociation kinetics occurring on biosensor surfaces * provides physical insights into reactions occuring on biosensor surfaces
A biosensor is a device for the detection of an analyte that combines a biological component with a physiochemical detector component. A typical biosensor consists of three parts: a sensitive biological element, a transducer in between and a detector element. The most widespread example of a commercial biosensor is the blood glucose biosensor, which uses an enzyme to break blood glucose down. In so doing it transfers an electron to an electrode and this is converted into a measure of blood glucose concentration. The high market demand for such sensors has fuelled development of associated sensor technologies. This book covers recent developments that combine the fields of biotechnology and electrical engineering with applications in the detection of very low levels of chemicals and biological agents in the body. It provides an authentic overview of a wide range of biosensing systems, discussing the elements of different transducers used in sensors and the selective elements that are employed. The style is relatively non-mathematical and informal in approach. The contents of the book will be ideal for graduate and postgraduate students of biotechnology, analytical and physical chemistry. It will also be invaluable to all those concerned with the environmental and biomedical applications of such biosensing systems.
This book describes the design, construction, optimization and applications of biosensors, including the biological component, its attachment to the transducer, and interfacing of the sensing element to appropriate electronic circuitry. In addition, typical applications of the sensor are described, along with any specimen pretreatment that may be necessary to remove interferences or ensure linearity of the sensor's response. A final chapter on the theoretical analysis of biosensor response characteristics is provided to aid in optimizing any device's performance. Biosensors provides an up-to-date account of techniques which today are being widely used by life scientists in universities and industry.
This reference text consists of contributed chapters by specialists directly carrying out research and development in this emerging field which joins advanced microelectronics with modern biotechnology. Chapters present novel biotechnology-based microelectronic instruments, such as those used for de
Biosensors are analytical devices that combine a biologically sensitive element with a physical or chemical transducer to selectively and quantitatively detect the presence of specific compounds. Balancing basics, principles, and case studies, Biosensors: Microelectrochemical Devices covers the theory and applications of one class of biosensor-microelectrochemical devices. The book clearly explains microelectronic techniques used to produce these cheap, fast reacting, and disposable sensors with the aid of helpful diagrams and tables. Researchers and postgraduates active in the field of chemical sensors, analytical chemistry, or microelectronics will find this an invaluable reference.
