Abstract
The detection of waterborne pathogens and toxins by biosensor-based methods are reviewed in this chapter. Descriptions of optical, electrochemical and electromechanical sensors are included to provide a broad perspective on these emerging devices. Surface chemistries for immobilizing biorecognition molecules on sensor surfaces are summarized. Further, biosensor-based detection methods for microbial contaminants are analyzed and discussed. Finally, representative sensor responses, limit of detections (LOD) and time to results (TTR) are compared and discussed read more ...
