Ultrasensitive electrochemical detection of uric acid based on cobalt-embedded nitrogen-doped carbon

Abstract

Based on the electro-oxidation mode, electrochemical sensors provide an appealing evaluation tool for uric acid (UA) detection. However, improvements in the field of high-performance electrocatalysts remain necessary to enable wide-range...

Flexible electronic materials and devices toward portable immunoassays

“…Biomarkers have been detected using a variety of electrochemical detection methods, including electrochemiluminescence, electrovoltammetry, potentiometry, impedance spectroscopy, OECTs, photoelectrochemistry, and FETs. [121][122][123][124][125] The Gleason group synthesized the -OH functionalized conducting copolymer of 3,4-ethylenedioxythiophene and 3-thiopheneethanol by oxidative chemical vapor deposition (Figure 10A). 100 They created a chemiresistive biosensing platform by fabricating flexible electrospun nylon fibers with a high surface area.…”

Surface Defect and Wettability Engineering of Porous SnOx for Reliable Bioassays with High Selectivity and Wide Linear Dynamic Range

“…A high-performance electrochemical bioassay system that provides rapid and selective detection of metabolites is of great importance in healthcare, pharmaceuticals, and clinical diagnostics. − The potential of the cascade reaction involving the oxidase catalytic reaction and the H 2 O 2 electrochemical reaction exhibits promising capabilities. − In this process, the analytes of interest are quantified by detecting the product H 2 O 2 , , which is generated through the catalytic reaction of aerobic oxidase. However, the catalytic reaction of oxidase typically occurs at the liquid–solid (electrolyte–electrode) diphase interface, where oxygen reactants are sourced from aqueous solutions .…”
