Numerical design of magnetic-field-gradient-guided branch targeting of Au/Ni–SiO 2 Janus microrobots in a bifurcating microchannel

Type: article

Abstract: , a reduction of approximately 54.5%. Mechanistic analysis showed that the increase in magnetic moment substantially exceeded the increase in hydrodynamic resistance, and the transport data for different Ni-layer thicknesses were largely represented by a common response using a dimensionless magnetic-guidance parameter. These results provide a quantitative basis for co-optimising microrobot magnetic structure, background flow and external magnetic actuation.
