- Phenolic compounds, such as catechol (CC), are highly toxic organics which can accumulate in the environment and the ecosystem. Therefore, there is great need for simple and real time detection of trace levels of CC in environmental samples. This paper describes the fabrication of a laccase biosensor to detect CC using a graphene-cellulose composite modified scree-printed carbon electrode. The sensor has linear sensitivity to CC over three orders of magnitude and detects CC in water samples. Follow-up funding from the Royal Academy of Engineering has allowed sensors to be field tested in Malaysia and Namibia.
