The distinguishing feature of the magnetic separation is the presence of long-range, dipole-dipole interparticle magnetic forces that may lead to undesirable microparticle clustering (chaining or amorphous aggregation) and deterioration of the magnetic separation quality if left unchecked (Rosensweig, 2014; Williams et al., 2010).

Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.
