After the morphology and SERS activity characterization, Au@Ag-MOFs were employed to sensitive and label-free detect <i>p</i>-chlorobenzaldehyde (PCB) in water samples. The pore structure and large surface area of Ag-MOFs shell results more adsorption of PCB, dragging more molecules to “hot spots” area. The abundant amino group in Ag-MOFs allows the occurrence of Schiff base reaction with aldehyde group in PCB. Taking the synergistic effect of both physical and chemical enhancement, SERS signals of PCB were greatly boosted. The method showed good linearity between 5.0×10<sup>−12</sup> M to 1.0×10<sup>−8</sup> M for PCB with the limit of detection (LOD) down to 3.3×10<sup>−12</sup> M.

However, the question of whether observed annotations are endogenous or artificial (i. e., from in-source fragmentation) is critical and has been largely unexplored in multimodal MSI. In matrix-assisted laser desorption/ionization (MALDI)-MSI datasets from researchers worldwide, PAs were found to represent up to 18 % of annotations in rat brain. Rat brain was additionally imaged here using nanospray desorption electrospray ionization (nano-DESI), a softer ionization strategy. No PAs observed with MALDI were present in the nano-DESI dataset. Further investigation strongly indicated lipid fragmentation to PAs for MALDI-MSI, but not with nano-DESI-MSI. We finally extend this observation to the MALDI-MSI analyses of human tissues, showing that PA annotations comprised up to 16 % of annotations. Therefore, this study shows that MSI annotations should be carefully interrogated, as in-source fragmentation or modification of lipids may contribute substantially to false annotations and incorrect biological interpretations.</p>","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"3 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/anse.202200112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50136194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The molecular structure and biological functions of lipids are intricately linked. Therefore, modern lipid analysis strives for complete structural elucidation and spatial mapping of individual species in tissues. Mass spectrometry is the uncontested key technology in lipidomics but cannot achieve this goal as a standalone technique. In particular, the distinction between frequently occurring isomers constitutes a major challenge. A promising step towards complete structural analysis of lipids consists in the coupling of mass spectrometry with laser light. Here we review recent advances in lipidomics applications employing laser-induced ultraviolet and infrared photodissociation and ion spectroscopy, which substantially increase the gain in structural information.

However, the disordered arrangement of probes and nonspecific adsorption of proteins in the biosensing interfaces for conventional biosensors often restricted the accessibility and recognition efficiency of probes towards targets, leading to poor detection performances (e. g., sensitivity and selectivity). Engineering of biosensing interfaces with functional molecules or nanomaterials has provided a promising molecular toolkit for enhanced accessibility and efficient recognition of biosensing probes. Among them, DNA has been an appealing material for interface engineering, because of its unique merits of biocompatible, predictable hybridization, and unparallel self-assembly ability. In particular, employing tetrahedra DNA nanostructures (TDNs) to engineer interfaces has been a powerful means to improve biosensor performance. Here, this review introduces the recent progress in TDN-based interface engineering. Then, we summarize the roles of TDNs in tailoring the properties of different interfaces, including electrode surface, channel surface, cell surface, etc., and highlight their biosensing applications.
