Metabolites are downstream end products of gene and protein activity that closely correlate with the phenotype of a biological organism. Therefore, by observing specific metabolic changes, one can gain insight into perturbations underlying disease.(8) Consequently, increasing attention has been dedicated to analyzing metabolites using MS in the context of clinical diagnostics, understanding disease mechanisms, and identifying new therapeutic targets. The ability to analyze metabolites directly from biofluids and tissues continues to challenge current MS technology, largely because of the limits imposed by the complexity of these samples, which contain thousands to tens of thousands of metabolites. A new technology being developed to address this challenge is Nanostructure-Initiator MS (NIMS), a desorption/ionization approach that does not require the application of matrix and thereby facilitates small-molecule (i.e., metabolite) identification.
