摘　　要：阐述了生物传感器在病原体检测中的意义、研究与进展,并提出了一种新型的基于纳米磁性材料磁致伸缩特性的生物传感器,即磁致伸缩纳米生物传感器(magnetostrictive nano-biosensor,MNBS)。与传统的生物传感器不同,MNBS传感器在外加磁场作用下不仅可以检测液态食物中的病原体,而且可以在非液态食物中位移,完成病原体的实时检测。此外,MNBS传感器检测周期短,操作简单,且检测成本低。完成检测后,MNBS传感器还可以在外加磁场的作用下,从食物中分离、回收,并可重复利用,大幅降低了经济成本。对MNBS传感器的制备工艺、病原体检测机制以及未来的发展方向等进行了详细说明。The significance, research and progress of biosensors for the pathogens detection in food are depicted. Besides, the magnetostrictive nano-biosensor （MNBS）, a novel biosensor based on the nano-magnetostrictive material is proposed. The conventional biosensors can only detect pathogens in the liquid-state food, while the MNBS biosensor can not only detect patho- gens in the liquid-state, but also move and detect in the non-liquid-state food under the magnetic field in real time. In addition, the MNBS has other advantages compared to the conventional biosenors, such as the shorter detection cycle, more convenient operation and lower detection cost. Even more, after the detection, the MNBS biosensor can be separated, collected and repeatedly used under the magnetic field, thus reducing the cost. The preparation process, pathogens detection mechanism and future research direction are also described in detail.
