This work reports an optical delivery of about 700-nm diameter polystyrene spheres along arbitrary bending nanofibers (600 nm in diameter) including complete loop structure. Dependence of bending loss on bending radii and central angles of the nanofiber has also been investigated. The results show that, for a specific input optical power, there is a corresponding minimum bending radius for optical trapping and delivery. In other words, for a specific input optical power, when the bending radius of the nanofiber is larger than the minimum bending radius, the 700-nm diameter nanospheres can be trapped and delivered along the bending nanofiber. Vice versa, the nanospheres will be escaped from the bending nanofiber during the delivery process because of relatively large bending loss.
