Herein we examined the toxicity, penetration properties and ability of Fe2O3·nH2O magnetic nanoparticles extracted from silt of the Borovoye Lake (Krasnoyarsk, Russia) to bind an antibiotic. Experimental studies were carried out using magnetic nanoparticles alone and after antibiotic exposure in tissue samples from nasal mucosa, cartilage and bone (in vitro). Toxicity of particles was studied i...

Since magnetic particles have unique features, the development of a variety of medical applications has been possible. The most unique feature of magnetic particles is their reaction to a magnetic force, and this feature has been utilized in applications such as drug targeting and bioseparation including cell sorting. Recently, magnetic nanoparticles have attracted attention because of their po...
