“…Additionally, with specifications, MBs could then function with different responsive groups, like tosyls, epoxyls, carboxyls, and amines which can be utilized to immobilize ligands with high affinity including antibodies, proteins, aptamers, among others, based on the accepted applications [6,39]. Recently, applications of magnetic separation have been introduced in biotechnology for analytical applications, separation of cells, sewage treatment, protein digestion and purifications [6,9,34,39]. Furthermore, integrating MBs with aptamers opens up additional opportunities in various applications including disease diagnosis using biosensors, cell imaging and labelling and magnetic resonance imaging, disease therapy, water purification, wastewater treatment, sewage treatment, and sample preparation [34,39].…”
