Biosensors for biological warfare agent detection

Biological warfare agents (BWA) such as Bacillus anthracis, Francisella tularensis, Yersinia pestis or butulotoxin represent one of possibilities exploitable by military or terrorists. Rapid detection of BWA is one of the most important presumptions prerequisities for successful defence against them. The detection devices-biosensors-can be divided according to their physicochemical transducers to electrochemical, optical, and piezoelectric groups. A comparison of classical detection methods with biosensors is also given.
