One of the problems that exist in the production of nanopreparation for biomedical application is to obtain a monodisperse fraction of magnetic nanoparticles. Currently, the size distribution is carried out by centrifugation. Due to the small mass difference nanoparticles separation of different fractions can last up to several days. In order to implement this process, requires costly equipment - ultracentrifuges. More productive process is magnetic separation because nanoparticles of different sizes differ significantly the value of the magnetic moment. Existing magnetic separation systems that work with micro- and nanomaterials intended for other tasks - separating the original product on the magnetic and nonmagnetic. By solving this problem is the development of magnetic separator Faraday system that is designed to highlight the source of the drug nanoparticles of 20...80 nm and development vysokohradiyentnoyi magnetic separation system, which is designed to extract nanoparticles narrower range - 40...60 nm. The methods of determining the parameters of magnetic separators. Numerical experiments in constructing trajectories nanoparticles separation channel separators confirmed that the methods can create magnetic separators that divide fractions nanoparticles.
