These efforts have resulted in significant improvements in sensor performance, particularly in terms of sensitivity and selectivity. Furthermore, the application of these recent advances has enhanced key sensor properties related to biofouling, long-term use, limit of detection, and wearability. Many research developments and reviews on electrical biosensors have already been published, covering topics such as their working principles, backgrounds, groundbreaking breakthroughs, and the challenges these chemical and biological sensors face. These reviews aim to provide a comprehensive understanding of electrochemical glucose sensors and their potential to improve healthcare outcomes.
