Mass spectrometry imaging (MSI) is a technique used in mass spectrometry to visualize the spatial distribution of molecules, as biomarkers, metabolites, peptides or proteins by their molecular masses. After collecting a mass spectrum at one spot, the sample is moved to reach another region, and so on, until the entire sample is scanned.

Mass spectrometry imaging (MSI) is a powerful tool that enables untargeted investigations into the spatial distribution of molecular species in a variety of samples.

Mass spectrometry imaging (MSI) [1, 2] is an emerging indirect visualization image technique, that supplies molecular distribution information by acquiring multipoint mass spectrometric data from biological tissues.

2 days ago · Fullerene-based nanoparticles have been extensively developed and applied in biological immunotherapy due to their unique immunomodulatory properties. However, current methods for investigating their biodistribution predominantly rely on fluorescent labeling, which limits our understanding of the true biodistribution of fullerenes at both organ and suborgan …
