SERS devices for the remote analysis of analytes

摘要

SERS-active materials are delivered to a remote zone, then optically interrogated to detect and analyze from a safe distance the presence of explosives or other materials which may or may not be hazardous. Delivery methods include deploying projectiles comprising SERS-active material(s) which distribute their contents upon deployment to a target zone.

主权项

1. An analyte detection system comprising
a. a device for deploying a deployable composition to a location to be analyzed, the deployable composition comprising SERS-active sites; and b. a Raman spectrometer configured to allow interrogation of the SERS-active surface of the SERS-active material on an analyte adsorbed thereon, wherein Raman spectrometer includes telescopic optics, comprising a telescopic lens, and wherein the telescopic optics comprises a fiber-optics light guide.
