摘要
随着神经递质多巴胺功能的研究加深,开发出基于二氧化铈(CeO2)纳米复合材料的多巴胺电化学传感器.CeO2的氧空位和可调电子结构促进了其电催化活性,复合非贵金属材料增强了传感器的灵敏度与稳定性.实验显示,传感器对多巴胺响应敏感且具选择性,实际应用中表现出良好的重现性和稳定性.DFT计算揭示了 CeO2在多巴胺检测中的作用,证明其在神经科学研究中的应用潜力.
Abstract
With the deepening of the function of the neurotransmitter dopamine,a dopamine electrochemical sensor based on ceria dioxide(CeO2)nanocomposite material has been developed.The oxygen vacancy and tunable electronic structure of CeO2 promote its electrocatalytic activity,and the composite non-precious metal materials enhance the sensitivity and stability of the sensor.The experiments showed that the sensor was sensitive and selective to dopamine response,and showed good reproducibility and stability in practical applications.DFT calculations revealed the role of CeO2 in dopamine detection,demonstrating its potential for application in neuroscience research.
