Paleoproteomics, the study of ancient proteins, is a rapidly growing field at the intersection of
molecular biology, paleontology, archaeology, paleoecology, and history. Paleoproteomics …

Organic carbon (OC) accounts for a large fraction of atmospheric aerosol and has profound
effects on air quality, atmospheric chemistry, and climate forcing. The molecular composition …

In the past decade, single-cell technologies have revealed the heterogeneity of the tumor-
immune microenvironment at the genomic, transcriptomic, and proteomic levels and have …

The striking finding that reaction acceleration occurs in confined‐volume solutions sets up
an apparent conundrum: Microdroplets formed by spray ionization can be used to monitor …

We discuss mini MS systems in terms of individual components and at a systems level.
Portable systems from academic and commercial laboratories are emphasized, but meso …

Metabolic heterogeneity of cancer contributes significantly to its poor treatment outcomes
and prognosis. As a result, studies continue to focus on identifying new biomarkers and …

When non-mass spectrometrists are talking about mass spectrometry it rather often sounds
as if they were telling a story out of Poe's Tales of Mystery and Imagi-tion. Indeed, mass …

MS has evolved as a critical component in metabolomics, which seeks to answer biological
questions through large-scale qualitative and quantitative analyses of the metabolome. MS …

A recent innovation in mass spectrometry is the ability to record mass spectra on ordinary
samples, in their native environment, without sample preparation or preseparation by …

Paper spray is developed as a direct sampling ionization method for mass spectrometric
analysis of complex mixtures. Ions of analyte are generated by applying a high voltage to a …
