摘要
食品检测策略的发展为确定食品中的污染物提供了机会。与其他应用策略相比,基于光产生的光学检测方法具有更高的灵敏度、选择性和快速性。在各种报告中,基于 DNA 的生物传感平台因其 DNA 形状和结构的多变性和灵活性而得到了广泛应用。DNA 结构以无标记和有标记两种形式应用于光学生物传感器。在本综述中,讨论了近年来用于检测食源性污染物的一些重要光学检测研究,重点是 DNA 在其结构中的作用。首先,简要介绍了影响最新进展的生物传感器中应用的 DNA 集成纳米结构。然后,在主要的分类食品污染物中,针对目标分析物介绍了基于 DNA 集成纳米结构的最重要的光学方法。最后,考虑了光学生物传感方法的前景和展望。
DNA integrated nanostructures for optical-based detection of foodborne contaminants
Development of food detection strategies provides chances for the determination of contaminants in foodstuffs. Optical detection approaches which are based on light generation brought several advantages compared other applied strategies with higher sensitivity, selectivity, and rapidness properties. Among different reports, DNA-based biosensing platforms have been applied dramatically due to their variability and flexibility nature of DNA shapes and structures. DNA structures have been applied in both label-free and labeled forms in optical biosensors. In the present review, some of the marked optical detection investigations in recent years are discussed for detection of foodborne contaminants with emphasis on DNA's role in their construction. First, applied DNA-integrated nanostructures in biosensors that impact the recent advancement are briefly described. Then, among the major classified food contaminants, the most important optical approaches based on DNA-integrated nanostructures have been presented for target analytes. Finally, the outlook and perspectives of optical biosensing approaches are considered.
