MagneStar, nano- and micro-sized magnetic particles developed by Nano-Micro Tech, are of great interest in biotechnology, biomedicine and catalysis applications. Nanomicro Tech is capable of supplying monodisperse particles of almost any size ranging from 5 nanometers to 1000 microns of different materials, structures, and functionalities.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. Nanomicro Tech has designed and produced magnetic nano- and microparticles for various applications. 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 prote…
