One of the most important aspects of nanoparticles in biomedical applications is their surface functionalization in order to improve their biocompatibility with biological entities, and Fourier infrared spectroscopy (FTIR) is very useful technique that provides information about iron oxides in their ground electronic state, and when this material is bonding with a polymeric coating provides information about mechanism of functionalized magnetic nanopartides. This technique is widely used in characterization nanopartides due to its simplicity and availability. In magnetite structure it provides information about the excitation of vibration or rotation of the trivalent and divalent iron cations and allows knowing the occupied sites when the divalent iron is replaced with other cations.

Among the magnetic materials that have found broad practical apvplication in technology, ferrites deserve attention. Ferrite nanopartides are the most explored magnetic nanopartides up to date. They are widely used in high-frequency applications, because an AC field does not induce undesirable eddy currents in an insulating material [3,4].To increase the recorded information density, it seems reasonable to obtain nanociystalline...

The potentialities of magnetic nanopartides in the biomedical field are now well established [45,46]. In vivo, these applications take advantage of three properties of these magnetic colloids (i) their field-induced mobility, which can be used for...

Block copolymers have been used as a template for creating nanopartide patterns. For example, some applications such as catalysis and magnetic recording necessitate a surface presentation for the nanopartides. For this approach, it is critical that the block copolymers present multiple blocks at or near the free interface. PS-b-PMMA, which has both PS and PMMA domains displayed at the surface at appropriate surface thickness, is frequently utilized for this reason. Figure 3(c) illustrates the selective adsorption of Au onto the PS domains, forming arrays of nanoscale clusters and wires. ...
