Rapid and label-free, electrochemical DNA detection utilizing the oxidase-mimicking activity of cerium oxide nanoparticles

We herein developed a simple and ultrafast electrochemical DNA detection method by utilizing the oxidase-mimicking activity of cerium oxide nanoparticles (CeO2). In the sensor, the presence of DNA, which electrostatically interacts with CeO2 and 3,3′,5,5′-tetramethylbenzidine (TMB) substrate, limits...
