摘要
荧光纳米材料因具有独特的发光性质,已成为分析检测等领域中极具应用前景的标记材料。分子印迹聚合物是一种人工合成的对特定模板分子具有较强特异识别能力"仿生"材料。分子印迹荧光纳米探针是将分子印迹技术的高选择性和荧光纳米材料的发光特性相结合,进而将微观分子识别过程转化为可读的荧光信号,具有识别选择性高、稳定性好、制备过程简单、灵敏度高、实用性强等特点。该类探针的研究对分析检测技术的发展具有积极推动作用。本文概述了分子印迹荧光纳米探针的检测原理及优点,重点介绍了该技术的分类及其近几年在食品安全检测方面的应用,并对发展趋势进行展望。
In recent years, fluorescent nanomaterials have been widely investigated as novel marking materials in the area of analysis and detection for their unique luminescent properties. Molecularly imprinted polymer is a type of artificial bionic material with robust specific binding ability to capture target molecules. The fluorescent molecularly imprinted nano probe combine the specific binding ability of molecularly imprinted polymer with luminescent properties of fluorescent nanomaterials, and can transform the microscopic molecular recognition process into a readable fluorescent signal.It also has the advantages of high selectivity, good stability, simple preparation process, high sensitivity and strong practicability. The exploration of these probes has a positive promoting in development of analysis and detection technology.In this review,the detection principle and advantages of fluorescent molecularly imprinted nano probe are summed up.The classification of the probe and its application in food safety and detection are then emphatically introduced. Finally, the future development trends of this technique are prospected.
