In this work, we investigated the crystal formation of anisotropic nanoparticles, namely Janus particles, at the water-oil interface using the dissipative particle dynamics simulation method. By considering three different interface templates, including planar, droplet, and rod, we observe an increase of the disorder-order transition packing fraction with increasing the curvature radius of the templates. Furthermore, the nanoparticles in the planar template assemble into a hexagonal lattice, while for the two remaining templates they aggregate into colloidsome-like structures.
