a Hydrodynamic trap (top view). b Floating trap (side view). c Light-induced bubble generation for droplets stabilized by f-Au@SiO2. The photothermal response of f-Au@SiO2 vaporizes the oil phase under laser illumination. The laser propagates along the +z direction. The expansion of the vapor bubble transferring momentum to push the droplet in a designated direction is applied to release the droplet trapped in a d hydrodynamic trap and e floating trap
