Development of an enhanced hybrid bi-catalytic electrode containing bimetallic composite catalyst and immobilized enzyme for complete glucose electrooxidation

Biosensors and Bioelectronics: X, 2023
We describe an enzymatic fuel cell (EFC) that can electrooxidize glucose completely. The EFC contains the hybrid Ni@Pt-CNT/OxOx bioanode, composed of a bimetallic composite catalyst (Ni@Pt-CNT) and the enzyme oxalate oxidase (OxOx), which can cleave ...

High-performance paper-based biocathode fabricated by screen-printing an improved mesoporous carbon ink and by oriented immobilization of bilirubin oxidase

Scientific Reports, 2022
In this study, the performance of a paper-based, screen-printed biofuel cell with mesoporous MgO-templated carbon (MgOC) electrodes was improved in two steps. First, a small amount of carboxymethyl cellulose (CMC) was added to the MgOC ink.

Wiring Xanthine Oxidase Using an Osmium‐Complex‐Modified Polymer for Application in Biosensing.

ChemElectroChem, 2022
Xanthine is a metabolite of interest as a medical and food freshness biomarker. We modified a screen‐printed electrode to detect this analyte by co‐entrapping xanthine oxidase (XOD) and an Os‐complex redox polymer over carbon nanotubes.
