Abstract:
Background and Aim

The aim of this study was the evaluate using of techniques LIBS (laser-induced breakdown spectroscopy) to detect biological agents in bioterrorism threat. Remote and real-time identification of biological agents is now one of the key needs for defense and security dimensions in the world.

Methods

In this study, has been used a descriptive method that after collecting the literature and the internet search.

Results

LIBS technique based on laser-induced plasma spectroscopy can lead to determining of amount various elements in the microorganisms. In this method, in place of laser focus was evaporate a small amount of the target surface and on the impacts of successive molecules in the vapor phase, was break the molecular bonds which the atoms and ions excited were create laser induced plasmas.

Conclusion

Detection of bioterrorism threats by means of light and simple at the online and distant is very important. According to the results of the research showed that LIBS technique is used to detect bioterrorism threats and its utilizations is being rapidly developed for the detection of biological agents.
