Magnetic particles can be manipulated by a magnetic field. Magnetic particles consist of a magnetic core or shell
mostly iron oxide and a polymer core or shell.As a biomarker assay they are used in medical applications. In a purification assay they can be used both in industrial and medical application.VDO Biotech magnetic microspheres development is mainly focussed are Chemiluminescence and Nucleic acid extraction. Currently VDO
s MA0308C and MS02H are most succesfully applied in Covid-19 assay development.
