摘要：
A magnetic manipulation technique based on a superimposed gradient magnetic field source for controlling magnetic nanoparticles in microfluidic channels was proposed. The designed magnetic field is composed of one gradient magnetic field generated by micro-electromagnetic coils positioned near a microfluidic channel and one external uniform magnetic field generated by large Helmholtz coil pairs. By controlling the configuration of Helmholtz coils, magnetic nanoparticles can be transported in different movement modes. As a proof of concept, the transport behavior of magnetic nanoparticles under different configurations of Helmholtz coils was successfully performed in two-dimensional (2D) geometries.
