SUMMARY:Conférence du professeur Facundo Fernández (Gatech)
DESCRIPTION:Titre : Forensics\, Metabolomics\, and Molecular Imaging by Ma
 ss Spectrometry.     La conférence sera prononcée par le professeur Fac
 undo Fernández de la School of Chemistry and Biochemistry du Georgia Ins
 titute of Technology.Résumé : Mass Spectrometry (MS) is one of the key 
 analytical methods used to identify and characterize small quantities of b
 iological molecules embedded in complex matrices.  Although MS has found 
 widespread use\, technical improvements in its instrumentation are needed 
 to extend its application to the grand challenges that face the environmen
 tal\, chemical and biomedical sciences. In this talk I present our progres
 s towards the use of MS for diagnosing ovarian cancer\, imaging algae meta
 bolites in tissues\, and rapidly detecting counterfeit drugs. I will also 
 present a variety of other applications that benefit from the high informa
 tion content provided by modern mass spectrometric experiments. More funda
 mental work involving finite element simulations and Schlieren imaging exp
 eriments of fluid dynamics at the atmospheric pressure interface of the ma
 ss spectrometer will be also presented\, and complemented with results fro
 m the ionization of 'thermometer molecules' to measure the degree of ion a
 ctivation during the ion generation process. Information supplémentaire
