Convenient and high-efficiency manipulation of nanoscale materials has huge potential applications in nano assembly and biomedical technology. We have reported an ultrasonic needle-droplet-substrate system to aggregate and then transport the nanoscale materials freely at the interface between the substrate and water droplet. In the manipulation method, the ultrasonic needle is inserted into the water droplet of nanoscale material to generate a controlled ultrasonic field for the manipulations. In this paper, we report the detailed method and results of FE (finite element) analyses for the investigation of working principle of the manipulation system. The FE analyses show that the ultrasonic needle can generate an acoustic streaming field around the ultrasonic needle to implement the nano aggregation and transportation. The computational results can well explain the experimental phenomena of multiple-function manipulation.
