Electrochemical detection of choline via oxygen consumption in a thermally reduced graphene oxide matrix: Advantages of operation at both positive and negative potentials

An amperometric choline biosensor was developed using synthesised thermally reduced graphene oxide (TRGO) as an efficient electrochemical surface and immobilisation matrix for choline oxidase (ChOx). The biosensor can operate via two distinct mechanisms depending on the applied working electrode pot...
