Publication number: 20140272946Abstract: Methods, systems, and devices for the detection and notification of chemical, biological, radiological, nuclear, and/or explosive agent. The detection and notification system uses aptamers bound to a catalyst that is activated when the aptamer binds to the agent. The activated catalyst acts on a substrate to create a signal that is detected, indicating the presence of the agent. For example, the system can be a glove worn by a user that includes a catalyst/substrate pair that, in the presence of the target agent, produces a colorimetric and/or fluorescent signal in a time-efficient manner.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: SRC, INC.Inventors: Adam J.
