It is suggested to search with combinations such as 'mass spectrometry imaging + ion source name (MALDI/DESI/SIMS/LDPI)' and 'spatial metabolomics ion source'; to focus on domestic matrix-free sources, add 'LDPI / label-free MSI / ambient MSI'. It is also suggested to follow conference abstracts such as ASMS and the annual meeting of the Chinese Mass Spectrometry Society.
When searching, distinguishing 'methodology papers' (new source/new parameters) from 'application papers' (spatial distribution of a disease/drug) helps quickly locate needed information; review articles suit building a field overview.
Recent high-frequency themes include matrix-free/ambient imaging, single-cell resolution, post-ionization sensitization, and multi-omics integration. The 'Industry News' column on the Neo-Source website provides technical interpretations of LDPI/DPI engineering features and single-cell, matrix-free trends, as supplementary reading from an engineering perspective.
When reading literature, cross-validate parameter claims: vendor nominal values (such as LDPI 2–3 μm, among the leading in the industry) and paper measurements should be considered together, avoiding equating promotional statements with independently verified results.
Methodology papers mostly report new ion sources, new post-ionization configurations, or how new scan parameters improve resolution/sensitivity; application papers show the spatial molecular maps of a disease, drug or species. The two complement: method decides what can be done, application decides what was done.
For engineering selection, the repeatability data and parameter boundaries in methodology papers are more valuable than a single application case; it is suggested to build your own literature matrix, classified by ion source × application × metric.
