Laser Chemistry

Our research group works on the development of Laser Techniques for analytical applications. Given the multidisciplinary importance and use of Laser-Induced Breakdown Spectroscopy (LIBS), we have successfully applied this technique to biological and geological samples, particularly with the identification and detection of pathogens for public safety-oriented applications, forensics environmental studies, and geology. The samples that have been studied include aerosols, human bones, and teeth, bacteria and fungi, swine tissues, honey, wine, milk, archaeological bones, speleothems, coral, and seashells.<br /><br />Mainly we investigate the atomic and molecular signatures generated by LIBS and the application of chemometric methods for the analysis of the data. During the past years where our group has advanced in exploring the LIBS technique in various fields, it has also shown great progress in the area of chemometrics. Further work includes the study of processes in the plasma through analytical data processing of the laser-plasma spectra, applying a broad range of chemometric tools.<br /><br />The members of our group have been engaged in theoretical and experimental research activities in various fields within the area of Laser Chemistry. We are particularly interested in laser ablation processes, and combining these with different techniques and analysis processes.

Development of spectroscopic techniques for analytical applications: This line of research focuses on the analysis and study of the composition of elemental materials using plasma spectroscopy generated by laser ablation (Laser-Induced Breakdown Spectroscopy, or LIBS). A priority aspect is the development of new methods and techniques of analysis, mainly focused on the detection and identification of elements and compounds in agri-food, environmental management, and security-oriented applications.<br />Statistical and mathematical methods applied to spectroscopy analysis: This research line deals with and studies different mathematical and statistical procedures applied to spectroscopic data processing, for both analysis and modeling. A priority aspect is the development of methods and instruments for industrial and quality control processes based on optical, spectroscopic, and luminescence techniques.
