Summary: Mass spectrometry imaging (MSI) enables the characterization of small-molecule metabolites within biological tissues. However, current matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has limitations. Surface-assisted LDI-MS (SALDI-MS) using the AuNP-hPDA-TDNT substrate shows superior performance for the detection and imaging of small biomolecules. The substrate has reduced background interference and allows visualization of various metabolites and lipids.

Summary: Traditionally, MALDI IMS requires the deposition of an organic matrix, which often generates high background noise in the low mass range. LDI offers selective ionization with low background in the low mass range. This article discusses the advantages and disadvantages of solvent free and wet deposition of metals as LDI matrices and demonstrates the power of metal-assisted LDI for analyzing low molecular weight molecules in tissue sections.

Summary: Timely screening and differential diagnosis of neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein associated disorder (MOGAD) are crucial for improving patients' quality of life. This study developed a fast metabolic fingerprint analysis method using nanoparticle-enhanced laser desorption/ionization mass spectrometry, which achieved high accuracy in diagnosing NMOSD and revealed comprehensive information about metabolic dysregulation. By combining metabolic fingerprints from plasma and cerebrospinal fluid, NMOSD and MOGAD could be effectively differentiated.

Summary: A wet-incipient impregnation method was used to synthesize hierarchical porous bimetallic (Co, Zn)-zeolitic imidazolate frameworks (ZIF-8)/TiO2 for efficient photocatalytic water splitting. Co@ZIF-8/TiO2 exhibited significantly higher photocatalytic efficiency than TiO2, with a hydrogen generation rate of 13 mmol·h(-1)·g(-1) and a 151-fold increase in catalytic performance. The hierarchical porous structure of Co@ZIF-8 facilitated charge transfer and provided efficient transport channels. This study demonstrates the potential of hierarchical porous metal-organic frameworks (MOFs) as support and promoter in photocatalytic applications of TiO2.
