ABSTRACT:
An evanescent-field sensor system and method of using the system to detect either liquid- or airborne biological pathogens, chemical agents, and other harmful or toxic species is provided. The sensor system involves 1) an evanescent-field sensor having a substrate surface with at least a partial bio- or chemo-responsive layer, which forms a part of a serially renewable sensing region; 2) an optical interrogation apparatus for monitoring the bio- or chemo-responsive layer; and 3) an air-fluid delivery system. The optical interrogation apparatus has a light source, an optical delivery system, and a detection instrument or device. The air-fluid delivery system includes either macro or micro-fluidic passages designed to convey biological or chemical analytes to a sensing region.
