Bioelectronics is an interdisciplinary field that includes elements of Chemistry, Biology, Physics, Electronics, Nanotechnology and Materials science. It ranges from the integration of biomaterials with electronics in recognition of sensing devices, such as biosensors, to the use of individual molecules to perform the electronic functions that semiconductor devices currently perform. The integration of biomaterials and electronics will affect a wide range of industries--for example the medical industry, with the development of advanced biosensors, biochips, artificial organs and prosthetics for sophisticated medical devices and diagnostics. The book is divided into four chapters--Bioelectronics, Biosensors, Biochips and Biocomputers, followed by references. It has been written in a simplified and easily understandable language, profusely illustrated with simple line drawings which are easily understandable and reproducible by the students. It is hoped that the book will be will received by the students, teachers and researchers in the field of Biotechnology.
