Abstract:Label-free electrochemical immunosensors based on screen-printed carbon electrodes are a promising tool for performing fast, simple and economical detection of cancer biomarkers.However, despite the potential of these devices, some limitations, such as their low sensitivity, need to be overcome before their widespread use as technology for clinical analysis. Herein, we proposed different strategies to modify screen-printed carbon electrodes, aiming to improve the analytical signal and the surface area for the … Show more
