Biosensor technology for detecting biological warfare agents: Recent progress and future trends

This review paper outlines the important issues with regards to the development of biosensors for the monitoring of biological warfare agents (BWAs) starting with the basic components of biosensors and the features of BWAs, which are compatible with detection using biological recognition molecules. The advantages and limitations of biosensors are discussed followed by the current state of the art in biosensors for detecting BWAs. Finally the developments required to enable biosensors to become more effective at providing early warning of possible biological attack and advances towards these developments are covered.
