Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Low‐density graphite electrodes have been covalently modified with gold nanoparticles and used as scaffold for the oriented immobilization of <italic>Myrothecium verrucaria</italic> bilirubin oxidase. The developed nanobioelectrodes have been tested as a biocathode in a human‐serum surrogate buffer that mimics physiological conditions. The nanostructured bioelectrode offered a −140 µA cm⁻² current density under serum‐mimic conditions at 0.2 V, and was operational during at least 6 days.</p> </abstract>
