摘要
共振能量转移(RET)是从受激或自发光供体到邻近基态受体(生色团猝灭剂或荧光团)的非辐射能量转移.利用该原理构建的生物传感器具有高灵敏度、高选择性、自动校正的特点,在环境检测领域具有巨大的应用潜力.本文综述了目前RET生物传感器在环境检测领域(包括重金属、阴离子、有机污染物、生物毒素和病原微生物的检测)的研究进展,并针对不同环境污染物分析了RET传感体系的构建特点,最后探讨了基于RET的生物传感器在环境领域应用所面临的挑战,并对其未来发展前景进行了展望.
Resonant energy transfer(RET)is a non-radiative energy transfer from stimulated or selfluminous donors to adjacent ground state receptors(chromophore quenchers or fluorophores).Biosensors based on this principle have the characteristics of high sensitivity,high selectivity,and automatic correction,and have great application potential in the field of environmental monitoring.In this paper,the research progress of RET biosensors in environmental monitoring(including the detection of heavy metals,anions,organic pollutants,biotoxins,and pathogenic microorganisms)is reviewed,and the construction characteristics of RET sensing systems for different environmental pollutants are analyzed.Finally,the challenges of RET-based biosensors in the environmental field are discussed,and its future development prospects are prospected.
