The non-enzymatic detection of the pollutant bisphenol A using S-graphene as nanozyme material

The sulfur-doped graphene (S-GR) acting as nanozyme material was used for the development of an electrochemical sensor for the sensitive detection of the pollutant, bisphenol A. The sensor was obtained by modifying the gold working electrode (WE) of a microfabricated device with the proposed S-GR nanomaterial. A wide linear concentration range and a low limit of detection LOD (1 nM) proved that the proposed method could be reliable to be used for on-site environmental application using portable instruments.
