text: Larive worked in the field of bioanalytical chemistry, applying analytical tools such as nuclear magnetic resonance spectroscopy (NMR) and mass spectrometry to the products of chemical separations. Much of her research focused on reducing the amount of sample needed for analysis, such as constructing microcoil NMR probes that can measure as little as 25 nL of sample and are usable as part of an capillary isotachophoresis apparatus. This has been applied to structure determination of heparin and heparan sulfate. She developed NMR pulse sequences to study protein ligand interactions in complexes with multiple ligands. She also researches analytical methods for metabolomics and chemogenomics for the reaction of plants to pesticides and hypoxia using NMR and mass spectroscopy.
  NMR is often thought of as a low-sensitivity method, but Larive's laboratory has developed ways of increasing the sensitivity of their measurements to obtain precise chemical and structural information. The techniques she has developed are relevant to understanding carbohydrate structure and biosynthesis, designing new drugs and measuring the purity of pharmaceuticals. Her work in developing chemical profiles for substances also has relevance for the authentication of foodstuffs such as wine, olive oil, and pomegranate juice.
