    Abstract : In this thesis, method development for improved analyte identification and throughput in mass spectrometry imaging (MSI) is discussed. In MSI, the spatial distribution of analytes from a sample is determined and visualized, information about the detected molecules interaction within the sample can thereby the deduced. READ MORE

  6. 4. Analytical developments and applications of ambient mass spectrometry imaging : Visualizing challenging analytes and understanding chemical mechanisms of ischemic stroke

    Author : Leonidas Mavroudakis; Ingela Lanekoff; Daniel Globisch; Malcolm Clench; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry imaging; ischemic stroke; mass spectrometry; isomers; spatial metabolomics; host-guest; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Bioanalytical methods that provide spatial information on molecular distributions are important for deep understanding of chemical mechanisms in health and disease. For instance, the localized action of drugs and metabolites can provide valuable information on metabolism in specific cellular regions, which would not be possible with bulk analysis. READ MORE
