Nanotechnology is a multifaceted technical and scientific field undergoing a fast expansion. Nanoparticles, quantum dots, nanotubes, nanorods, nanowires, nanochips and many more are being increasingly used for fabrication of nanosensors and nanobiosensors to increase the sensitivity and selectivity of reactions. Food safety is an extremely important concern in food industries since it is directly associated with effect of food on human health. Here in our review, we have not only described the newest information regarding methods and use of nanomaterials for construction of nanosensors but also their detection range, limit of detection (LOD) and applications for food safety. Precise nanosensors having improved sensitivity and low limit of detection were discussed in brief. Review is primarily focused on nanosensors employed for detection of adulterants and contaminants in food products such as meat products, milk, fruit juices and water samples.
纳米技术是一个多方面的技术和科学领域，正在快速发展。纳米粒子、量子点、纳米管、纳米棒、纳米线、纳米芯片等越来越多地被用于制造纳米传感器和纳米生物传感器，以提高反应的灵敏度和选择性。食品安全是食品工业中极其重要的关注点，因为它直接关系到食品对人类健康的影响。在我们的综述中，我们不仅描述了关于纳米材料用于构建纳米传感器的最新信息，还描述了它们的检测范围、检测限（LOD）和在食品安全方面的应用。简要讨论了具有提高的灵敏度和低检测限的精确纳米传感器。综述主要集中在用于检测食品产品中的掺杂物和污染物的纳米传感器，如肉类产品、牛奶、果汁和水样。
