Most of the microparticle magnetic separations take place in aqueous solutions, whose viscosity plays an important role in the dynamics of the microparticle separation processes. Considering that the magnetic force on the magnetic microparticle decreases faster with its linear dimension (as a cube function of its diameter) than its friction coefficient (as a

2022year8month18day The magnetic force in biomagnetic separation processes therefore depends on: how the magnetic field changes spatially (i.e., the magnetic field gradient) the strength of the magnetization of the magnetic beads. When you select the conditions for scaling up your magnetic separation process, it’s important to remember that the
