Abstract:
The rapid detection technology in food safety plays a vital role in the field of preventive medicine.The traditional physical and chemical detection methods have some limitations,such as costly,difficult to operate and high requirements on environment,can not meet the needs of quality and safety on-site rapid screening,and are gradually replaced by emerging sensor detection technologies.The aptamer-upconversion biosensor technology is a novel rapid detection technology,which is based on the combination of functionalized upconversion nanomaterials and aptamer technology.Compared with the traditional immunofluorescence technology,it has advantages in sensitivity,specificity and stability,and is widely used in rapid detection.In this paper,the upconversion luminescence and aptamer technologies were briefly introduced,and the aptamer-based upconverting phosphor biosensing technology and its application in rapid detection of food safety were summarized.Based on the current research status,the bottleneck and the future development trend of this technology were analyzed,which provides a reference for the application of this technology in food safety and other fields.
