Biosensors (Hardcover)

Descripción:

Hardcover. The field of biosensors was born out of the collaboration between scientists from a variety of different disciplines: physicists, chemists, biologists, electronic engineers, computer scientists, mathematicians and engineers. All of these scientists should be able to consult this work without any difficulty and find information to complement their original training. This tutorial introduction should be a useful reference in everyday work. Sensors are studied and described and the techniques for immobilizing enzymes, cofactors, mediators, micro-organisms, immunoagents and organelles are all outlined. The fundamental principles of the subject are reviewed and the practical aspects of design and fabrication for each of the major classes of biosensor are discussed. A significant part of the text is devoted to enzyme sensors, as these have been extensively studied and are now commercially available. Principle applications such as medical instrumentation and environmental monitoring are also explored with attention to the economics of the technology. This book provides a coherent tutorial introduction to biosensors for engineers and research and development workers involved in sensor development and application.

Sinopsis:

Reseña del editor: 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.
