Magnetophoresis in microfluidic lab: Recent advance

Microfluidic technology has shown great application prospects in biochemical analysis, drug delivery, disease diagnosis, and other fields. Magnetophoresis is an effective means to manipulate particles in liquid media by using magnetic field force. This combination forms a simple, effective, high-throughput, and low-cost bioparticle analysis technology. In this paper, we explain the basic principles of magnetophoresis technology and analyze the two key parts of magnetophoresis equipment, liquid medium and magnetic field source. Then, we classify current mainstream magnetophoresis techniques, review the research and applications of magnetophoresis in particle mixing, focusing and separation in recent years, and analyze the key parameters affect the performance of magnetophoresis. Finally, in view of the limitations of current magnetophoresis technology, we offer an outlook on possible future development directions.
