| الوصف: | A laser-induced breakdown spectroscopy technique for analyzing biological matter for the detection of biological hazards is investigated. Eight species were considered in our experiment: six bacteria and two pollens in pellet form. The experimental setup is described, then a cumulative intensity ratio is proposed as a quantitative criterion because of its linearity and reproducibility. Time-resolved laser-induced breakdown spectroscopy (TRELIBS) exhibits a good ability to differentiate among all these species, whatever the culture medium, the species or the strain. Thus we expect that TRELIBS will be a good candidate for a sensor of hazards either on surfaces or in ambient air. |
