MagneStar® magnetic particles are developed by Nano-Micro. These particles are of great interest in the fields of biotechnology and biomedicine. Such magnetic nanoparticles are very useful in effective separation of biomolecules, cells, and as a catalyst support. For example, magnetic microparticles pre-coated with antibodies against specific cell surface antigens can be used for cell separation. Nanomicrotech has designed and produced magnetic nano- and microparticles containing different functional groups such as carboxyl, hydroxyl, and amino groups for various applications. In addition, Protein A modified magnetic particles are also available for purification of protein antibodies.
Another type of MagneStar® has a core-shell structure in which the core is a magnetic compound, and the shell is either inorganic or organic material. The surface of the particle is equipped with various functional groups such as amino, epoxy, carboxyl acid, and hydroxyl, etc. for different applications. These magnetic particles have large specific surface area and high magnetic content.

Particle Structure:
MagneStar® is a series of products of magnetic particles with narrow size distribution and super paramagnetism. These small magnetic particles have a core, and a layer of magnetic compound sandwiched between the core and an outermost layer. The outermost layer of the particles is either inorganic or functionalized organic material, which completely covers the magnetic compound to prevent it from potentially incompatible interaction with biomaterials. These magnetic particles have a very good dispersity with well controlled particle size and narrow particle size distribution.
