Screen-printed electrodes as versatile electrochemical sensors and biosensors

Screen printing or thick film technology is a widely know approach to manufacture disposable and low-cost sensors and biosensors. Screen-printed electrodes can be manufactured with diverse conductive inks, shapes, and dimensions, depending on the analytical need. Besides their fabrication, these platforms are suitable to be customized with a variety of (nano)materials and bioelements. Herein, we highlight the use of several electrochemical sensors and biosensors for application in the environmental, food, and clinical field, taking as case-studies those devices that have been realized using polyester as substrate.
