【摘要】 炸药及其痕量检测技术已成为当今国际反恐领域的研究热点之一。常用的传感器如声表面波传感器、离子迁移谱传感器等,在检测指标方面还达不到实际应用的要求。石墨烯基炸药传感器检测限达10-10,有响应快、灵敏度高等优点,已逐渐成为研究的焦点。简要分析了石墨烯在传感器中应用的优越性。重点介绍了近年来石墨烯基炸药传感器(包括电化学、表面增强拉曼散射和荧光共振能量转移及电化学发光传感器)的研究进展。总结了现有石墨烯基炸药传感器的技术特点。认为对石墨烯及氧化石墨烯表面修饰及功能化,开发性能优良的石墨烯杂化材料,提高其检测灵敏度是今后研究的方向。更多还原

【Abstract】 Explosive and its trace detection technology has become one of research hotspots in the field of current international anti-terrorism.All kinds of sensors,such as surface acoustic w ave sensors and ion mobility spectrum sensors,used to detect explosives,can not meet the requirements of practical application in the detection indicators. T he graphene based explosive sensors w ith detection limit by 10- 10have the advantages of fast response and high sensitivity and have gradually become the focus of research. In this paper,the superiorities of graphene in the sensor application w ere briefly analyzed. T he progresses of study about graphene based explosive sensors,including electrochemical,surface enhanced R aman scattering( SER S),fluorescence resonance energy transfer( FR ET),and electrochemical luminescence( EC L) sensors w ere emphatically introduced in recent years. T he technical characteristics of existing grapheme based explosive sensors w ere summarized.C onsidering that the surface modification and functionalization of graphene and graphene oxide( GO),development of graphene hybrid materials w ith excellent performance and improvement of the detection sensitivity are the direction of future research.更多还原
