Abstract
A method of detecting and identifying bacteria, micro-organisms or plants in a liquid or gaseous medium, the bacteria, micro-organisms or plants being of the kind which produce signaling molecules in intercellular space, includes positioning a biosensor in the liquid or gaseous medium, the biosensor having a biolayer matched to specific signaling molecules to be detected whereby the biolayer is reactive thereto in a manner which varies operation of the sensor. Such variation of the operation of the biosensor is detected to thereby determine the presence and purpose of the bacteria, micro-organisms or plants in the liquid or gaseous medium.
