Abstract: Magnetic particles play an important role in current technology, and this field of
technology extends to a broader progression. The term magnetic particles typically cover the
paramagnetic particles and super-paramagnetic particles. Various materials like iron oxide are
common, but other materials are available as well; a survey of such materials has been included
in this work. They can serve for technological purposes like separation and isolation of
chemical products or toxic waste, their use in the diagnosis of pathologies, drug delivery and
other similar applications. In this review, biosensors, bioanalytical devices and bioassays,
have been discussed. Materials for magnetic particles preparation, methods of assay, biosensors
and bioassays working in stationary as well as flow-through arrangements are described
here. A survey of actual literature has been provided as well.
