superparamagnetic NPs can attract each other when placed in external magnetic eld
gradient while they could form stable colloids in the absence of the eld. The large sur-
face area of the magnetic NPs provides an excellent platform to interact with molecules
in solution. After the reaction on the surface, the magnetic NPs can be separated expos-
ing them to magnetic eld gradients. Tagging the magnetic NPs is possible via chemical
modication of the surface of the magnetic NPs. There are a number of specic magnetic
separation techniques used depending on the purpose of the magnetic separation. ...
