Abstract
A magnetic separation filter has an unsupported magnetically soft material layer having a plurality of pores, and, optionally, a passivation layer disposed on the magnetically soft material layer. The magnetic separation filter may be part of a microfluidic device having a lateral flow channel and a vertical flow magnetic separation filter. The magnetic separation device may be used to separate magnetically tagged particles, such as cells.
