我们开发了一种湿化学程序，将 10-40 nm 胶体金纳米颗粒附着在扫描探针显微镜 (SPM) 探针尖端的顶部，使单纳米颗粒相互作用的实验成为可能。这种颗粒附着过程非常灵活，可以进行修改以附着不同种类和尺寸的纳米颗粒。单纳米粒子端接的尖端在各种其他应用中也具有潜力，例如光学和磁性模式 SPM 的增强灵敏度探针。
We have developed a wet-chemistry procedure to attach a 10-40 nm colloidal gold nanoparticle to the top of a scanning probe microscopy (SPM) probe tip, making experiments of single nanoparticle interaction possible. This procedure of particle attachment is flexible and can be modified to attach nanoparticles of different kinds and sizes. The single-nanoparticle-terminated tips also have potential in various other applications, such as probes of enhanced sensitivity for optical and magnetic modes SPM.
