Dry Deposition Strategies for MALDI-MS Imaging: Principles, Advances and Emerging Applications.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Matrix-assisted laser desorption/ionisation mass spectrometry imaging (MALDI-MSI) has become a pivotal tool in biomedical research, enabling untargeted, spatially resolved analysis of molecular species in complex biological tissues. Among the critical steps in MALDI-MSI workflows, matrix deposition significantly influences sensitivity, spatial resolution and reproducibility by affecting crystal morphology and analyte extraction efficiency. While wet deposition techniques, such as manual spray-coating, electrospray deposition and automated systems, have been widely adopted, they often suffer from limitations related to solvent-induced analyte delocalisation. These challenges have driven increasing interest in dry matrix deposition methods, which aim to eliminate or minimise solvent use to enhance spatial fidelity and image quality. This review summarises the main dry deposition strategies used in MALDI-MSI, covering their principles, instrumentation, benefits and limitations. It also discusses recent comparative studies (2023-2025) between wet and dry approaches, examining their impact on analytical performance and the increasing importance of dry deposition in high-resolution spatial omics.
