Preparation of a flexible glucose electrochemical sensor and its detection in elderly diabetic patients
Abstract
The study proposes a diabetes detection scheme based on a novel flexible glucose electrochemical sensor for the current situation of diabetes management in China, especially for the elderly diabetic population. The sensor is fabricated using optimized conductive materials and diluents with set printing parameters. It mainly realizes non-invasive monitoring of human blood glucose by detecting human sweat, thus effectively detecting elderly diabetic patients. Simulation experiments showed that the sensor had a detection limit of 7.33 μM (S/N = 3) and a high sensitivity of 23.5 μA mm−2 for simulated sweat, demonstrating good stability and durability. Moreover, in the actual in vitro detection experiments, the sensor detected elderly diabetic patients with an accuracy of more than 98.3%. In addition, the response time of the sensor was very short, only 10.5 s to complete a detection, which was suitable for elderly patients. The above illustrated that the flexible glucose electrochemical sensor prepared in the research had certain feasibility and accuracy in the blood glucose monitoring of elderly diabetic patients. The research results not only provide theoretical basis and technical support for the preparation of flexible glucose electrochemical sensors, but also provide new ideas and methods for blood glucose monitoring and treatment of elderly diabetic patients.
