Acoustic radiation forces (ARFs) on three-layered micro-shells (TLSs) are investigated using Mie scattering theory. The TLS is proposed to simulate a nucleate cell with nucleus, cytoplasm, and membrane. It is found that the existence of the inner core or outer shell greatly influences ARFs on nucleate cells. We focus on the influences of the geometry, acoustic parameters, and the surrounding medium on ARFs on TLSs. With increasing inner core radius or outer shell thickness, the ARF on the TLS shows a distinct increase. We find that the impedance of each layer of the TLS plays a dominant role with regard to the ARF, while the density and the sound velocity separately provide distinct modulations. In addition, it is found that the higher impedance of the surrounding medium induces larger ARF on the TLS. Our work may be beneficial for the acoustic manipulation of nucleate cells.
