Interfacial metal nanoparticles show rapid and autonomous locomotion from air/water to oil droplet/water interfaces. Facile and robust method for 3D assembly of colloidal metal nanoparticles at oil droplet/water interface is proposed based on this interesting observation. Interfacial transfer of nanoparticles produces up to 20‐fold denser 3D assembly and the assembly exhibits 100‐fold amplification of Raman signal compared with nanoparticle monolayer.
