The separation of micron size components of suspensions according to the size and density of the particles is presently an intractable problem. However, by using a magnetized ferrofluid it should be possible to generate unique particle trajectories for each combination of particle size and density. This study investigates the potential of this strategy for separating such particles, laying the foundation for new small-scale diagnostic "lab-on a chip" technology that could be used in biotechnology to study whole blood, or in mineral processing to control energy intensive ball mills for mineral particle liberation.

根据颗粒的尺寸和密度分离悬浮液的微米级组分目前是一个棘手的问题。然而，通过使用磁化的铁磁流体，对于颗粒尺寸和密度的每种组合，应该可以产生独特的颗粒轨迹。本研究探讨了这种策略分离这些颗粒的潜力，为新的小规模诊断“芯片实验室”技术奠定了基础，该技术可用于生物技术研究全血，或用于矿物加工，以控制能量密集型球磨机米尔斯释放矿物颗粒。
