摘　　要：利用金纳米颗粒独特的光学特性,设计了一种基于氨基磺酸修饰后的单一稳定分散的金纳米颗粒,在遇到水合肼之后发生聚集,从而引起了检测体系溶液颜色的变化,这种变化肉眼就可以观测到,从而实现了对实际样品中的水合肼快速、灵敏、重现性高的现场实时检测。A single stable dispersed gold nanoparticle modified based on sulfamic acid was designed,which was using the unique optical properties of gold nanoparticles,and after encountering hydrazine hydrate,the color of the monitoring system solution was changed,which can be observed by the naked eye.The rapid,sensitive and reproducible real-time detection of hydrazine hydrate in real samples was realized.
