Thus, in the competitive fluorescence-quenching lateral flow immunoassays (FQ-LFIAs), the fluorescence quencher with an outstanding optical property is of great importance. Herein, gold nanoparticles (AuNPs) and polydopamine (PDA) coengineered covalent organic frameworks (COF/Au@PDA) were synthesized as a fluorescence quencher to increase spectral overlap. Thanks to the excellent visible light absorption of COF with donor–acceptor (D-A) structure, the localized surface plasmon resonance (LSPR) capability of AuNPs, and the broad light absorption of the PDA layer, the COF/Au@PDA exhibits intense absorption and a full spectral overlap toward aggregation-induced emission luminous (AIE) dots. Thereafter, COF/Au@PDA, with its immense potential to completely quench the fluorescence of AIE dots through primary IFE and secondary IFE, was applied to a bimodal LFIA platform for verification with a nitrofurazone metabolite as a model analyte. As expected, the detection sensitivity of the COF/Au@PDA-based FQ-LFIA (turn-on) is improved by 6-fold compared with that of the colorimetric (CM)-LFIA (turn-off). Further, ChatGpt was used to improve the assay accuracy and sensitivity, utilizing its high sensitivity to subtle changes in LFIA signals, especially for weak signals that are indeterminate with the naked eye. This work offers a potential approach for building a high-performance fluorescence quencher in the FQ-LFIA and indicates the potential for the application of artificial intelligence in highly sensitive LFIAs.","PeriodicalId":27,"journal":{"name":"Analytical Chemistry","volume":"24 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As principal optical trapping objects, microbeads can combine optical tweezers with suspension array technology, with amply focused laser beams and adequately concentrated tags contributing to highly sensitive detection. In view of the inefficiency of conventional single-trap optical tweezers, multitrap systems are developed. Here, green- and blue-emitting core–shell–shell upconversion nanoparticles (UCNPs) are adopted to encode microbeads and determine dual miRNAs, with the internal shells leading the luminescence process to facilitate quenching through luminescence resonance energy transfer (LRET). Utilizing the trans cleavage of CRISPR/Cas12a, quenched luminescence signals are recovered and amplified, causing further enhanced detection sensitivity. Ultimately, limits of detection (LOD) of 17 and 22 aM are obtained with excellent specificities verified. Furthermore, dual miRNAs from MCF-7, A549, and MCF-10A cells are extracted and detected, with results consistent with those obtained by PCR. Notably, miR-155 in MCF-7 and A549 cells is detectable at the single-cell level. Thus, the differences in the measured miRNA levels between MCF-7 and MCF-10A cells imply the potential of this method to discriminate breast cancer cells from epithelial cells despite the difficulty in distinguishing different cancer cells due to similar miRNA levels.","PeriodicalId":27,"journal":{"name":"Analytical Chemistry","volume":"14 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Near-infrared fluorescence (NIRF) imaging could potentially address the clinical challenges of PDAC. Indocyanine green (ICG) has been widely used in clinical practice; however, its short half-life and lack of active targeting greatly limit its application in pancreatic surgery. In this study, the active targeting peptide KTLLPTP (which actively recognizes PDAC cell surface overexpression Plectin-1) was modified to the ICG to create the novel contrast agent ICG-PTP, which actively targets PDAC cells. It was successfully applied to the NIRF imaging of the PDAC orthotopic mice model, achieving an improved tumor signal background ratio (T/N ratio) of 4.28, compared to 2.34 in the free ICG group. Next, Fluorescence-guided excision of subcutaneous/orthotopic PDAC using ICG-PTP was performed, accurately identifying the tumor margin and significantly facilitating resection efficiency. Finally, PDAC metastases were identified, and interventional photothermal ablation (iPTA) was performed under fluorescence laparoscope guidance. ICG-PTP exhibits good biosafety and clinical transitional potential. Thus, they can provide surgeons with efficient real-time tumor information and offer new treatment strategies for metastases. Accordingly, modification of probes for clinical use and adaptation studies of current equipment are the current focus.","PeriodicalId":27,"journal":{"name":"Analytical Chemistry","volume":"36 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A circulating form of soluble FAP has also been identified in the serum, becoming a biomarker for pan-cancer diagnosis and prognosis. However, the current peptide substrate-based enzymatic activity detection or antibody-dependent detection methods have been hindered by insufficient selectivity and complex operations, so it is valuable to develop effective nucleic acid aptamers as FAP affinity ligands. In order to deeply explore the biomimetic recognition technology, this study proposed an elaborate aptamer screening strategy for targeting the protein characteristic structure. Taking the glycosylation of the FAP protein as a target, four FAP-specific aptamers with high performance were successfully generated. Further, using the champion aptamer as a recognition tool and combining it with ultrasensitive detection technology-surface enhanced Raman scattering (SERS), a novel dual aptamer-based sandwich sensor was constructed for the rapid determination of FAP. Due to the dual-specific recognition of the orthogonal aptamer pair, the sandwich method obviously improved the selectivity to FAP protein, with a maximum cross-reactivity of less than 8% and a quantitation limit of 100 pg/mL. It was conveniently applied in high-sensitive and high-selective detection of serum FAP in cancer patient samples. Therefore, the research of this study not only opens new access for the selection of antiglycan aptamers but also boosts the application of the FAP aptamer as a recognition tool in cancer diagnostics.","PeriodicalId":27,"journal":{"name":"Analytical Chemistry","volume":"107 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of these approaches have leveraged initial mass spectrometry imaging (MSI)-based spatial metabolomics to inform the region of interest (ROI) selection for downstream spatial proteomics. However, these workflows have been limited by varied substrate requirements between modalities or have required analyzing serial sections (i.e., one section per modality). To mitigate these issues, we present a new multiomic workflow that uses desorption electrospray ionization (DESI)-MSI to identify representative spatial metabolite patterns on-tissue prior to spatial proteomic analyses on the same tissue section. This workflow is demonstrated here with a model mammalian tissue (coronal rat brain section) mounted on a poly(ethylene naphthalate)-membrane slide. Initial DESI-MSI resulted in 160 annotations (SwissLipids) within the METASPACE platform (≤20% false discovery rate). A segmentation map from the annotated ion images informed the downstream ROI selection for spatial proteomics characterization from the same sample. The unspecific substrate requirements and minimal sample disruption inherent to DESI-MSI allowed for an optimized, downstream spatial proteomics assay, resulting in 3888 ± 240 to 4717 ± 48 proteins being confidently directed per ROI (200 μm × 200 μm). Finally, we demonstrate the integration of multiomic information, where we found ceramide localization to be correlated with SMPD3 abundance (ceramide synthesis protein), and we also utilized protein abundance to resolve metabolite isomeric ambiguity. Overall, the integration of DESI-MSI into the multiomic workflow allows for complementary spatial- and molecular-level information to be achieved from optimized implementations of each MS assay inherent to the workflow itself.","PeriodicalId":27,"journal":{"name":"Analytical Chemistry","volume":"52 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142869987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiplex PCR amplification was employed to enrich 20 gene regions, with sequencing performed on either the Oxford Nanopore Technologies (ONT) or Illumina platforms. Customized bioinformatics pipelines provide a streamlined process from raw data to clinician-friendly reports. The ONT tNGS method has been optimized, and its performance has been thoroughly evaluated, utilizing Q20+ chemistry in combination with the R10.4.1 flow cell. It requires only 15 high-quality reads per target gene to accurately identify all variants, with the turnaround time taking 4 h and 50 min. Studies confirmed that this method effectively identifies <i>Mycobacterium</i> species and was highly resistant to interference from other clinical pathogens. To ensure optimal coverage, it is recommended to input at least 500 copies of the genome and sequence 500MB of high-quality FASTQ data. Diagnostic performance evaluations demonstrate that this method achieves 98.35% concordance with phenotypic drug susceptibility testing (pDST) and is consistent with the results obtained from Xpert MTB/RIF assays. The design of long amplicons not only ensures comprehensive coverage of target regions but also simplifies primer design, facilitating compatibility with various sequencing platforms.
