In summary, we report the synthesis of butterfly-shaped nanoparticles (GNBs) and discuss their synthesis mechanism via an additive-effect approach. The GNBs demonstrated the possibility of designing a nanodevice for interfering with the early stage of droplet formation and on-demand photodispersion of droplets via NIR-laser irradiation. The detailed investigation of the formation of moderately symmetrical nanoparticles represents an essential insight for other appropriate nanodevices for controlling small biological nanostructures, as well as the facet control of nanomaterial syntheses to produce additional sophisticated structures .
