Abstract: Biosensor technology is a powerful alternative to conventional analytical techniques, harnessing the speci?city and sensitivity of biological systems in small, low cost devices. Despite the promising biosensors developed in research laboratories, there are not many reports of applications in agricultural monitoring. The authors review biosensor technology and discuss the different bio-receptor systems and methods of transduction. The difference between a biosensor and a truly integrated biosensor system are de?ned and the main reasons for the slow technology transfer of biosensors to the marketplace are reported. Biosensor research and development has been directed mainly towards health care, environmental applications and the food industry. The most commercially important application is the hand-held glucose meter used by diabetics. The agricultural/veterinary testing market has seen a number of diagnostic tests but no true biosensor systems have made an impact. The need for fast, on-line and accurate sensing opens up opportunities for biosensors in many different agricultural areas }in situ analysis of pollutants in crops and soils, detection and identi?cation of infectious diseases in crops and livestock, on-line measurements of important food processing parameters, monitoring animal fertility and screening therapeutic drugs in veterinary testing. Future challenges in the commercial development of biosensor are also addressed. 2003 Silsoe Research Institute. All rights reserved. Published by Elsevier Science Ltd
