In fact, one of the major benefits of magnetic separation is that ...

The magnetic separation is a physical separation technique which is based mixtures or using the magnetic properties of the material, such as its sensitivity to the attraction or repulsion magnets. It is also known as magnetization, because the objects that can be separated by this technique are magnetized by the magnetic field of the magnets.

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.

Magnetic Separation Process. The magnetic separation equipment releases a current through the coil within the machine creating a magnetic field. This in turn magnetizes the steel matrix inside the machine. As material flows through the magnetized matrix, all magnetic material is captured, and the non-magnetic material passes through.

The final compound, Fe 3 O 4 @SiO 2, was washed in ethanol and then collected through a magnetic separation procedure. The second method is the silica deposition from silicic acid solution, and through this method, the particle size can be effectively controlled. Additionally, a higher percentage of the MNPs' surface can be covered.

Magnetic cell separation has become a popular technique to enrich or deplete cells of interest from a heterogeneous cell population. One important aspect of magnetic cell separation is the degree to which a cell binds paramagnetic material. It is this paramagnetic material that imparts a positive magnetophoretic mobility to the target cell, thus allowing effective cell separation. A ...
