基于纳米材料构筑的金属离子荧光传感器克服了传统荧光传感器检测能力弱,稳定性不足,检测条件受限制等缺陷,为金属离子的检测提供更加灵敏、准确的方法。构筑金属离子荧光传感器的纳米材料主要有金属纳米粒子、量子点、磁性纳米粒子、硅纳米材料、碳纳米材料等,针对近年来基于这些纳米材料构筑的金属离子荧光传感器的制备、结构、性能以及应用进行了综述,同时展望了基于纳米材料的荧光传感器的发展前景与方向。

Metal-ion fluorescence sensors based on nano-materials can overcome the defects brought by the traditional fluorescent sensors such as weak detection ability,insufficient stability and limited detection conditions,and provide a more sensitive and accurate method for the detection of metal ions.The nano-materials for preparing metal-ion fluorescence sensors are mainly composed of metal nanoparticles,quantum dots,magnetic nanoparticles,silicon nanomaterials and carbon nanomaterials etc.In this paper,the preparation,structure,properties and application of metalion fluorescence sensors based on these nano-materials in recent years are reviewed.At the same time,their development prospect and direction are expected.
