摘要：

Laser induced breakdown spectroscopy (LIBS) has become a powerful tool for the direct analysis of a large variety of materials in order to provide qualitative and/or quantitative information. However, there is a lack of information for LIBS analysis of biological samples. In this work, the spectra of E. coli, nutritional medium and filter paper have been analyzed by nanosecond LIBS. The samples were identified obviously by comparing the spectral intensity and varieties of trace mineral elements. The results showed efficient discrimination of E. coli by LIBS technique.
