A new electrochemical sensor for organophosphate pesticide (methyl-paraoxon) detection based on bifunctional cerium oxide (CeO2) nanozyme is here reported for the first time. Methyl-paraoxon was degraded into p-nitrophenol by using CeO2 with phosphatase mimicking activity. The CeO2 nanozyme-modified...
