Abstract

The TMs were suggested to be useful in future cancer treatment by magnetic targeting combined with drug release in response to hyperthermia.

Magnetic Polystyrene Nanoparticles with a High Magnetite Content Obtained by Miniemulsion Processes

“…[1,2] Several kinds of magnetic polymer nanoparticles have been produced from both natural and synthetic polymers with the intention to incorporate groups on the surface or to treat their surface to perform, for instance, selective separations. In special, magnetic nanoparticles with or without polymer encapsulation can be used as magnetic drug targeting, [3,4] tissue engineering, magnetic resonance imaging, [5] and hyperthermia. [6] There are also several applications for mechanical and electrical devices which take advantage of the magneto-rheological properties of ferrofluids, e.g., in loudspeakers, seals, sensors, dampers, etc.…”

Encapsulation of nanosized magnetic iron oxide by polyacrylamide via inverse miniemulsion polymerization

“…Due to the widespread applications of magnetic polymeric particles, especially in biological field, such as cell separation [1][2][3][4][5], site-specific drug delivery [6,7], tissue engineering [8] and nucleic acids concentration [9,10], more and more attentions have been paid to preparation of different kinds of magnetic polymeric particles in the past decades, and various strategies have been performed to producing magnetic polymeric particles.…”

Magnetic microparticle steering within the constraints of an MRI system: proof of concept of a novel targeting approach

“…Up to ten magnets (8×4×2 cm or 3×3×1 cm) resulted in a total field of at least 0.5 T and in general 0.8 T. (Lemke et al 2004) Dextran magnetite (DM) particles 5-10 nm (average 8 nm) incorporated inside thermosensitive magnetoliposomes (1.16+−0.37 μm) Coercivity=240 A/m, magnetic susceptibility 0.3 (gFe) −1 , saturation magnetization=0.1 Wb/m 2 .gFe and T2 relaxivity=220 l.mmol −1 .s −1 .

“…Ever since, most of the research effort seems to have been placed on particles and carriers development (Alexiou et al 2001(Alexiou et al , 2002Babincova et al 1999Babincova et al , 2001Babincova et al , 2002Babincova et al , 2004Lemke et al 2004;Morales et al 2005;Nobuto et al 2004;Viroonchatapan et al 1995) while the targeting and tracking methods remained almost unchanged.…”
