Research and Expertise

  • Research Interests
    Dan Armstrong has over 500 publications, including twenty book chapters, one book ("Use of Ordered Media in Chemical Separations") and eight patents.  He has been named by the Scientific Citation Index as one of the world's most highly cited scientists, and he has given over 350 invited seminars and colloquia worldwide.  Daniel Armstrong is considered the "Father" of micelle and cyclodextrin-based separations, he elucidated the first chiral recognition mechanism by cyclodextrins, he was the first to develop macrocyclic antibiotics as chiral selectors, and he is one of the world's leading authorities on the theory, mechanism, and use of enantioselective molecular interactions.  Over 30 different LC and GC columns that were originally developed in his laboratories have been commercialized and/or copied worldwide.  His work and columns were in part responsible for the chromatography and electrophoresis-lead revolution in chiral separations over the last one and one half decades.  Currently, the columns, chiral selectors and techniques he developed dominate the world of analytical enantiomeric separations.  Recently, he developed the first high efficiency CE separation approach for microorganisms (i.e., bacterial, viruses, fungi, etc.).  This will extend the realm of separation science into the mainstream of biology and colloid science.  He also has developed the most effective way to characterize the solvent properties of room temperature ionic liquids (RTILs).  This has proven to be an essential and effective way to explain the effect of RTILs on organic reactions, and in various analytical methodologies.  Surfactant aggregation to form normal micelles in RTILs was demonstrated.  The first MALDI-MS matrices and high stability GC stationary phases were also developed.  Most recently, chiral RTILs have been shown to produce enantiomeric excesses from racemates and prochiral molecules via solvation effects.  These solvation effects also change the luminescence behavior of chiral molecules.
