摘要:

将生物电化学传感器材料引入本科实验教学中,结合前沿科研成果设计了综合探究性化学实验——三维氮掺杂碳纳米球的制备及在谷胱甘肽检测中的应用。以三聚氰胺和炭黑为原材料,通过一步高温热解法制备了三维氮掺杂碳纳米球。通过电化学技术手段研究材料的生物传感性能,在最优化条件下成功实现了生物分子谷胱甘肽的分析检测。该实验设计充分体现了“制备合成–结构表征–分析应用”的科研逻辑思维模式,培养本科生科研自主创新能力,进而从整体上提升本科生的基本实验技能和综合应用能力。

Abstract:

A comprehensive exploratory chemical experiment is designed to introduce carbon-based bioelectrochemical materials into undergraduate experimental teaching. This experiment consists of preparing three-dimensional N-doped carbon nanospheres (3D-N-CB) and applying them in the electrochemical detection of glutathione. First, 3D-N-CB was synthesized via one-pot pyrolysis using melamine and carbon black as the raw materials. Subsequently, the bioelectrochemical sensing performance of 3D-N-CB was studied using various electrochemical techniques, and glutathione detection was successfully achieved under optimal conditions. This experiment can fully embody the scientific research thinking mode of synthesis-characterization-application. And it can cultivate the ability of undergraduate students to innovate independently in scientific research. Therefore, the experiment can effectively improve the basic experimental skills and comprehensive application ability of undergraduates.

Key words: Bioelectrochemical sensor, Comprehensive exploratory experiment, N-doped carbon nanospheres, Glutathione
