从理论上比较了微流控磁场梯度过滤器中磁珠之间的磁相互作用和水动力相互作用，发现水动力相互作用的范围更大，并且占主导地位。流体动力学的相互作用有助于捕获带有磁珠标记的粒子，因为这些粒子相互拖动，可能会减轻对磁性参数的要求。(c) 2005年Elsevier B.V.出版
Magnetic and hydrodynamic interactions between magnetic beads in microfluidic magnetic field gradient filters are compared theoretically and we find that the hydrodynamic interactions are of a longer range and dominate the magnetic ones. Hydrodynamic interactions aid the capturing of particles tagged with magnetic beads as the particles drag each other along, possibly easing requirements on magnetic parameters.
