    摘要： Raman scattering of radiation applied to a water sample is used to assess occurrence of a pathogen in the sample. The method is useful for detecting pathogens that are difficult to detect using other methods, such as protozoa. Examples of organisms that can be detected in water samples using these methods include protozoa of the genus Cryptosporidium and the genus Giardia. The methods described herein have important applications, such as for detection of Cryptosporidium organisms in municipal water systems.

    摘要： The disclosure provides for a system and method for detecting a threat agent. A sample is illuminated to produce photons Raman scattered and emitted by the sample. The Raman scattered photons are collected using time-gated detection without collecting the emitted photons. A Raman spectroscopic data set is generated from said Raman scattered photons wherein said Raman spectroscopic data comprises at least one of a Raman spectrum and a Raman chemical image. The Raman spectroscopic data is assessed to thereby determine the presence or absence of a threat agent in the sample. The sample may be in a target area. The sample may be illuminated using a pulsed laser or an intensity modulated laser. The illumination source may be synchronized with a gating element that enables time-gated detection.
