Bilirubin Oxidase-Based Nanobiocathode Working in Serum-Mimic Buffer for Implantable Biofuel Cell

Authors:María Cristina Gutiérrez Sánchez, Marcos Pita Martínez, Miguel D Toscano , Antonio López de Lacey
Groups of research:BioElectroCatalysis
Low-density graphite electrodes have been covalently modified with gold nanoparticles and used as scaffold for the oriented immobilization of Myrothecium verrucaria 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 mAcm2 current density under serum-mimic conditions at 0.2 V, and was operational during at least 6 days
