New directions in screen printed electroanalytical sensors: an overview of recent developments

Screen printing is widely used to fabricate disposable and economical electrochemical sensors and has helped us to establish the route from 'lab-to-market' for a plethora of sensors. We overview recent developments in the field where screen printed electrochemical sensors are utilised. Starting with their fundamental understanding, through to highlighting new developments in bulk metal and mediator modified electrodes, as well as novel advantageous electrode designs, we demonstrate the wide and diverse range of applications that sensors based on this fabrication approach have achieved.
