Nanoscience is one of the most important research and development frontiers in modern science. Nanotechnology is now widely used throughout the pharmaceutical industry, medicine, electronics, robotics, and tissue engineering. The use of nanoparticle (NP) materials offers many advantages due to their unique size and physical properties [1]. Nanoparticles have been used to deliver drugs to target tissues and to increase stability against degradation by enzymes. The superparamagnetic nanoparticle is one of these nanoparticles, which can be manipulated by an external magnetic field to lead it to the target tissue [2]. Based on their unique mesoscopic physical, chemical, thermal, and mechanical properties, superparamagnetic nanoparticles offer a high potential for several biomedical applications, such as [3–5]: (a) cellular therapy such as cell labelling, targeting and as a tool for cell-biology research to separate and purify cell populations; (b) tissue repair; (c) magnetic field-guided carriers for localizing drugs or radioactive therapies; (d) magnetic resonance imaging (MRI); (e) tumor hyperthermia; (f) magnetofection. Furthermore, special surface coating of the magnetic particles require, which has to be not only non-toxic and biocompatible but also allow a targetable delivery with particle localization in a specific area. Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumor using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia. The release mechanism of drugs, the diffusion coefficient and the biodegradation rate are the main factors which govern the drug release rate. Here, drugs may be bound to the nanoparticles either within the production process of nanoparticles or by adsorption of drugs to nanoparticles [6]. Particles were injected into a certain part of the body and a magnet was placed close to the point of injection, such that the particles were retained at the location of the magnet. Moreover, by placing the magnet in the vicinity of some organs or extremities it was possible to increase the concentration of the drugs at that position. Another field of medical applications where magnetic nanoparticles are very useful is magnetic resonance imaging (MRI) [7]. Because of their tendency to accumulate with different density
