Title Third-generation oxygen amperometric biosensor based on Trametes hirsuta laccase covalently bound to graphite electrode

English abstract
The response of low-density graphite electrodes hosting Trametes hirsuta laccase in a direct electron transfer regime is presented for real-time analysis of O2 concentrations. The use of contrasting immobilisation methods developed for biocathodes affords good reproducibility and reliability of the amperometric biosensor, which shows a limit of detection below 1 µM and a sensitivity slightly higher than 60 nA cm−2 M.
