The development of micro glucose sensors plays a vital role in the management and monitoring of diabetes, facilitating real-time tracking of blood glucose levels. In this paper, we developed a three-layer core-sheath microwire (NW@CuO@CoO) with nickel wire as the core and copper oxide and cobalt oxide nanowires as the sheath. The unique core-sheath structure of microwire enables it to have both good conductivity and excellent electrochemical catalytic activity when used as an electrode for glucose detecting. The non-enzymatic glucose sensor base on a NW@CuO@CoO core-sheath wire exhibits a high sensitivity of 4053.1 μA mM cm, a low detection limit 0.89 μM, and a short response time of less than 2 s.
微型葡萄糖传感器的发展在糖尿病的管理和监测中起着至关重要的作用，有助于实时跟踪血糖水平。在本文中，我们开发了一种以镍丝为芯、氧化铜和氧化钴纳米线为鞘的三层核壳微丝（NW@CuO@CoO）。微丝独特的核壳结构使其在用作葡萄糖检测电极时具有良好的导电性和出色的电化学催化活性。基于NW@CuO@CoO核壳丝的非酶葡萄糖传感器具有4053.1 μA mM cm的高灵敏度、0.89 μM的低检测限和小于2 s的短响应时间。
