Abstract:In this paper, a metalloperoxidase Cu2MoS4 is introduced, which can replace horseradish peroxidase (HRP), and the double enzyme system composed of lactic acid oxidase (LOD) can respond linearly in the physiological concentration range (10—25 mmol · L−1 ). Based on this two-enzyme system, a simple and low-cost wearable paper sensor was prepared to monitor the change of lactic acid content in human sweat, so as to observe the health level of human body in real time. This sensor is simple in preparation and small in size, and can be attached to the skin with medical bandage. Because of its simple structure, it can be customized to meet the needs of users.
Key words:wearable sensor; LOD; HRP; Cu2MoS4; lactate detection
