Basic magnetic particles can be further coated and functionalized for biotechnology and biomedical applications. In vitro, magnetic beads are widely used in diagnostic and separation of biomolecules, such as protein, cell, DNA/RNA, microorganism. In vivo, magnetic beads have been used both in therapeutic (drug delivery and hyperthermia) and diagnostic applications (magnetic resonance imaging(MRI)). https://www.cd-bioparticle...
