The scientific understanding and technological development of environmental biosensors have been advancing, but their commercialisation has usually been slow. However, their situation has been improving during recent years, as several more technologies have been demonstrated in the field. Advances have been made in their signal transducer technology, sensitivity, and miniaturised detection systems. Several market obstacles remain; for example, some of the advances also improve competing technologies. Therefore, a critical issue for the commercial success of biosensors is their ability to find unique cost, convenience, and performance advantages in the competitive environmental monitoring market. A biosensor has a biological recognition element and a signal transducer. Recognition elements are usually biocatalytic (enzymes), bioaffinity (antibodies, receptors, DNA), or micro-organisms. Transducers include electrochemical, optical, and acoustic devices. This article describes some recent progress on biosensors, and covers: (1) currently available systems; (2) biosensor development challenges; (3) chemical substances and biological parameters for whose detection biosensors have been reported; (4) biosensors being developed; (5) future developments; and (6) biosensor information and support.
