纳米传感器在食品检验中的应用

Applications of nanosensors in food inspection

文中综述了纳米传感器的作用原理和在食品检验中的应用。通过回顾利用纳米传感器检测食品包装内气体、食品中小分子和食源性致病菌的研究成果,总结得到纳米传感器与传统检验方法相比,具有选择性强、精确度高、检测时间短等优势,且可在不破坏食品包装的情况下实现对食品质量的动态监测,在食品检验中将有巨大的发展潜力和应用价值。然而,这项技术尚不能取代传统的食品检验技术,纳米传感器材料成本控制,纳米材料向食品中的迁移及食用安全性评价,纳米传感器与宏观世界的沟通等问题,是这项技术发展过程中有待解决的课题。

The mechanisms and applications of nanosensors in food inspection were reviewed in this paper.The recent trends of nanosensors for detections of gasses in package,small molecules and pathogens in food were also introduced.Compared to traditional detection methods,nanosensors had capability to bind and separate targets more accurate,more specific and less time.Furthermore,nanosensors can be used in dynamic monitoring of food quality without destroy food packages.Nanosensors would have more great developments and applications on food inspection in the future.However,it cannot replace the traditional detecting methods.The cost,the migrating of nanomaterials in food and safety evaluations,the transduction between nanosensors and the macro- world are all the questions need to be solved.
