Gold Nanoparticles-Based Colorimetric Immunoassay of Carcinoembryonic Antigen with Metal–Organic Framework to Load Quinones for Catalytic Oxidation of Cysteine

Sensors, Год журнала: 2024, Номер 24(20), С. 6701 - 6701

Опубликована: Окт. 18, 2024

This work reported gold nanoparticles (AuNPs)-based colorimetric immunoassay with the Cu-based metal–organic framework (MOF) to load pyrroloquinoline quinone (PQQ) for catalytic oxidation of cysteine. In this method, both Cu2+ and PQQ in MOF could promote inducer cysteine by redox cycling, thus limiting cysteine-induced aggregation AuNPs achieving dual signal amplification. Specifically, recombinant carcinoembryonic antigen (CEA) targets were anchored on through metal coordination interactions between hexahistidine (His6) tag CEA unsaturated sites MOF. The CEA/PQQ-loaded be captured antibody-coated ELISA plate catalyze However, once target samples bound antibody immobilized surface, attachment would limited. Cysteine remaining solution trigger cause a color change from red blue. concentration was positively related AuNPs. signal-on competitive plasmonic exhibited low detection limit linear range 0.01–1 ng/mL. Note that most proteins commercial kits are His6 N- or C-terminal, so provide sensitive platform biomarkers.

Developing sensitive and highly active nanozymes for antioxidant analysis is of the utmost significance in medical diagnosis health monitoring due to their essential roles as free reactive oxygen species scavengers. Here, six metal-organic frameworks (MOFs)-based are developed a dual-mode absorbance/image colorimetric sensor array simultaneous discrimination determination various antioxidants with comparable structural or chemical properties. The catalysts exhibit wide range potent oxidase-like catalytic activities, verified by kinetic parameters, presence dispersed transition metallic bimetallic redox nodes. These efficiently catalyze oxidation colorless 3,3',5,5'-tetramethylbenzidine (TMB) blue TMBox, resulting noticeable absorption RGB color changes at 650 nm. Various demonstrate different reducing capabilities leading generation fingerprint-like spectral patterns. pattern recognition chemometrics methods including principal component (PCA) linear discriminant (LDA) represent well-separated clustering ascorbic acid, dopamine, uric cysteine, glutathione, thiocyanate, tannic gallic acid. assay provides detection (0.1-75 μM) limits low 30 nM. successfully discriminated concentrations, mixtures, interferences. Furthermore, sensor's applicability biologically relevant was validated urine plasma samples. Overall, MOF-based nanozyme offers promising platform discriminating determining potential applications.
