Functional Magnetite Nanoparticle: A Review on the Particles Lysis and Nucleic Acid Separation

The functional magnetite nanoparticles are one of the most important functional materials for nucleic acid separation. Cell lysis and magnetic separation are two essential steps involve in optimizing nucleic acid extraction using the magnetic beads method. Many coating materials, coupling agents, chemical cell lysis, and several methods have been proposed to produce the specific desired properties for nucleic acid extraction. The important properties, such as biocompatibility, stability, linking ability, hydrophobicity, and biodegradable, were considered. The appropriate coating material of magnetite core and coupling agent are necessary to give biomolecules a possibility to link with each other through chemical conjugation. In this review, progress in functional magnetite nanoparticles to optimize the high binding performance in nucleic acid extraction is discussed.
