The early magnetic separation techniques used particles consisting of an iron-oxide core coated with silane. The surface of the particles was then bound to molecules containing a free carboxylic acid, which in turn bound to DNA or RNA. The salt concentration determined the strength of the bonds between functional groups and the …

Multiplex magnetic particles separation can improve the bioanalysis efficiently, which can be used in a diverse range of fields. In addition, it should be noted that this model is only applicable for low particle concentrations cases. Interparticle interactions can influence the separation significantly when dense suspensions are employed.
