Electrocatalysis of cerium metal-organic frameworks for ratiometric electrochemical detection of telomerase activity

Synthesis and characterization of nanoceria for electrochemical sensing applications

“…The proposed biosensor showed a wide range of telomerase activity between 2 × 10 2 and 2 × 10 6 cells per mL with a detection limit of 27 cells per mL. 128 …”

“…The proposed biosensor showed a wide range of telomerase activity between 2 Â 10 2 and 2 Â 10 6 cells per mL with a detection limit of 27 cells per mL. 128 A higher catalytic of nanoceria embedded in amorphous carbon and associated with chitosan-lactate oxidase was offered to employ it as a lactic acid biosensor. Oxidation of lactic acid by lactate oxidase produced by H 2 O 2 was measured with CV on the gold electrode.…”

Ratiometric Electrochemistry: Improving the Robustness, Reproducibility and Reliability of Biosensors

“…Their chain elongation properties have been incorporated into biosensor design for the facile detection of cancer cells. Lei et al utilised cerium metal organic frameworks (Ce-MOFs), labelled with AuNPs and capture DNA to detect telomerase activity (Figure 9a) [30]. An MB-labelled hairpin was immobilised onto a AuE, with a hybridised telomer proximal to the electrode, and the hairpin conformation bringing the MB label close to the electrode surface.…”

A ratiometric electrochemical strategy based on Fe (iii) and Pt (iv) for immobilization-free detection of Escherichia coli

“…28 Briey, dual-signal ratiometric measurements show great promise at the chemotherapeutic, cellular and animal levels. [29][30][31] Therefore, the application of a double signal ampli-cation strategy and ratiometric electrochemical method can further improve the detection sensitivity and selectivity of the sensor.…”
