  1. 1. Applications of nanospray desorption electrospray ionization mass spectrometry In situ lipid and metabolite analysis from cells to tissue

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hilde-Marléne Bergman; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; mass spectrometry imaging MSI ; nanospray desorption electrospray ionization nano-DESI ; single-cell analysis; neurotransmitter imaging; diabetic nephropathy; pneumatic nebulization; lipidomics; metabolomics; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : Ambient mass spectrometry (MS) has proved to be an important addition to the bioanalytical toolbox. These methods perform analyte sampling and ionization under atmospheric pressure, and require very little sample preparation other than the sampling process in front of the machine. LÄS MER
