Firstly, as the core halloysite nanotubes were functionalized with magnetite nanoparticles.

Most clinical laboratories currently use qualitative methods to detect IgM antibodies; however, these have limitations in determining disease severity and progression. Thus, a quantitative IgM assay is required to enhance clinical diagnosis and treatment. Therefore, we employed the principle of the capture method for detecting rubella virus (RV) IgM. RV IgM was captured using anti-human IgM antibodies immobilized on magnetic beads, followed by adding Tm<sup>3+</sup>-labeled RV detection antigen, before performing inductively coupled plasma mass spectrometry (ICP-MS) analysis. The method demonstrated excellent linearity with a correlation coefficient (R<sup>2</sup>) of 0.9944 and a detection limit of 5 U/mL. Precision testing showed that the coefficients of variation (CV) for the low-concentration and high-concentration samples were 11.73% and 6.79%, respectively. Interference studies have shown that the bias from common interfering substances is less than 10%, and the method exhibits high specificity. The daily stability test results remained within 10%, while the recovery rate ranged from 95.25% to 102.43%. The reference interval for negative samples was less than 215.36 U/mL, and the kappa consistency test between our method and the electrochemiluminescence immunoassay method showed strong agreement, with a value of 0.86 (>0.75).

Herein, this study demonstrates that carbonylated covalent organic frameworks (COFs) with pore-matching capabilities can serve as promising interference-resistant adsorbents for the rapid and efficient capture of ISDs (cyclosporin A (CsA), tacrolimus (FK-506), and rapamycin (RPM)) from complex whole blood matrices. Under optimized conditions, MCOF-2-COOH, with a pore size 1.5 times the diameter of the drug molecule, demonstrated superior ISDs adsorption performance, achieving an adsorption capacity of up to 84.95 mg g<sup>-1</sup> in 10 min. Instrumental characterization and theoretical calculations elucidated the potential adsorption matrix, revealing that the COF provides multiple forces, including hydrogen bonding, electrostatics, and π-π interactions, with the carboxyl site playing a crucial role. This study provides both a theoretical basis and experimental evidence for the use of COF materials in the selective adsorption of drugs from complex matrices, as well as a strategy for designing functionally customized COFs for drug therapy monitoring applications.</p>","PeriodicalId":462,"journal":{"name":"Analytical and Bioanalytical Chemistry","volume":" ","pages":"3447-3464"},"PeriodicalIF":3.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
