1 Introduction Catheter Ablation has become an essential therapy for atrial fibrillation (AF), with better efficacy in maintaining sinus rhythm, improving symptoms, and enhancing the quality of life compared to medical therapy [1, 2]. The electrical isolation of the pulmonary veins (PV) is widely considered as the cornerstone ablation strategy [3, 4].

The spatial distribution of diverse biomolecules in multicellular organisms is essential for their physiological functions. High-throughput in situ mapping of biomolecules is crucial for both basic and medical research, and requires high scanning speed, spatial resolution, and chemical sensitivity. Here we developed a tissue-expansion method compatible with matrix-assisted laser desorption/ionization mass-spectrometry imaging (TEMI). TEMI reaches single-cell spatial resolution without sacrificing voxel throughput and enables the profiling of hundreds of biomolecules, including lipids, metabolites, peptides (proteins), and N-glycans. Using TEMI, we mapped the spatial distribution of biomolecules across various mammalian tissues and uncovered metabolic heterogeneity in tumors. TEMI can be easily adapted and broadly applied in biological and medical research, to advance spatial multi-omics profiling. Tissue-expansion method compatible with mass-spectrometry imaging (TEMI) enables the profiling of lipids, metabolites, peptides, proteins, and N-glycans in complex tissues with high spatial resolution, advancing spatially resolved multi-omics mapping.

AbstractSingle-atom catalysts (SACs) have attracted significant interest due to their exceptional and tunable performance, enabled by diverse coordination environments achieved through innovative synthetic strategies. However, various local structures of active sites pose significant challenges for precise characterization, a prerequisite for developing structure-activity relationships.
