英文摘要：

Nanogold labeling is a highly sensitive,high-throughput,and highly efficient labeling technique that has been used to detect pathogens.Nanogold particles can serve as markers.These markers can be quickly separated from a complex sample so that the desired product can be purified and concentrated.Advantages of this technique are its speed and small size.This paper reviews the physical and chemical properties of gold nanoparticles,how they are prepared,and how they are used to detect pathogens.
