Via a soft lithography method under an external magnetic field and using a nanocrystalline growth technique, oblique two-tier conical structures with different oblique angles of the cones are fabricated successfully. Compared to a previous study, the directional bouncing of droplets with the lowest energy loss can be realized on the OTCSs and the transport distance can be controlled by changing the OAs of the cones.
