Matrix-assisted laser Desorption/Ionization Mass Spectrometry Imaging (MALDI MSI) is an analytical technique used for the spatial mapping of drugs, explosives, and organic samples, making it a game-changer in Forensic examination. It detects a wide range of biomolecules in their native state without specific tags, antibodies, labels, and dyes. This review aims to highlight the advancement of MALDI-MSI over time and its impact on Forensic Science due to high-resolution molecular imaging.

Purpose: To assess the impact of autologous serum (AS) tears at a 50% concentration on the ocular surface of patients with refractory dry eye disease (DED) because of Sjogren syndrome.
Methods: Twenty eyes of ten patients with severe immune-mediated DED were contralaterally randomized to receive either AS tears 50% or artificial tears between June 2021 and May 2023. Changes in tear stability, ocular surface staining, and in the morphology of the corneal sub-basal nerves were evaluated before treatment and at 1, 2, and 3 months after treatment using objective tests for DED and confocal microscopy.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants that have been in use industrially since the 1940s. Their long-term and extensive commercial use has led to their ubiquitous presence in the environment. The ability to measure the bioconcentration and distribution of PFAS in the tissue of aquatic organisms helps elucidate the persistence of PFAS as well as environmental impacts.

Unlabelled: Rapid and accurate identification of cultured molds is important to determine clinical significance and therapeutic decision-making. Conventional mold identification uses phenotypic macroscopic and microscopic characterization; however, this can take days or weeks for colony maturity and definitive microscopic structure formation, be limited to genus-level identification, and be misidentified due to morphologic mimics or similarities between closely related species. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) revolutionized bacterial and yeast identification but remains uncommon for molds in part because of limited reference libraries.

Bovine coronavirus (BCoV), a significant cattle pathogen causing enteric and respiratory diseases, is primarily detected using reverse transcription-polymerase chain reaction. Our objective was to develop a novel detection method for BCoV by matrix-assisted laser desorption/ionization‒time-of-flight mass spectrometry (MALDI-TOF MS). Peptide mass fingerprint analysis revealed that nucleocapsid (N), membrane (M), and hemagglutinin-esterase (HE) were three main BCoV proteins.
