“…Recently, Rodríguez-López et al reported magnetic IONPs with controlled size distribution were electrochemically synthesized by applying a dissymmetric pattern of potential pulses to iron-based electrodes in aqueous media. It was found that Fe 3 O 4 NP formation was favored, while avoiding the formation of metallic Fe particles with more anodic potentials and the longest time [ 113 ].…”

This review focuses on the recent development and various strategies in the preparation, microstructure, and magnetic properties of bare and surface functionalized iron oxide nanoparticles (IONPs); their corresponding biological application was also discussed. In order to implement the practical in vivo or in vitro applications, the IONPs must have combined properties of high magnetic saturation, stability, biocompatibility, and interactive functions at the surface. Moreover, the surface of IONPs could be modified by organic materials or inorganic materials, such as polymers, biomolecules, silica, metals, etc. The new functionalized strategies, problems and major challenges, along with the current directions for the synthesis, surface functionalization and bioapplication of IONPs, are considered. Finally, some future trends and the prospects in these research areas are also discussed.

“…Hence, the charged particles are accelerated towards the electrode surface and tend to collide with each other to form an aggregate. Under pulsed potential or pulsed current, the motion of particles due to the two forces are stopped at the off-condition that prevents particles collision and, in turn, particles agglomeration (Rodríguez-López A. et al, 2012).…”

“…In general, the proposed mechanisms can be divided into four groups although the detail steps for each group may be different. They are (i) iron hydroxide reduction at the cathode (Cabrera L. et al, 2008;Ibrahim M. et al, 2009;Rodríguez-López A. et al, 2012;Ying T.Y. et al, 2002), (ii) hydrogen gas as a reducing agent of iron hydroxide (Franger S. et al, 2004;Manrique-Julio J. et al, 2016;Melnig V. and Ursu L., 2011), (iii) direct reaction between Fe 2+ and Fe 3+ (Karami H. and Chidar E., 2012;Ying T.Y.…”

Magnetite (Fe 3 O 4 ) is one of the most important iron oxides due to its extensive range of application in various fields. The characteristics of magnetite can be considerably enhanced by reducing the particle size to the nanometer scale. When novel functions of nanoparticles are desired, it is necessary to have monodispersed or nearly monodispersed nanoparticles. Many synthesis methods have been proposed to produce monodispersed magnetite nanoparticles, including co-precipitation, sol-gel, hydrothermal and electrochemical methods. In this review, progress in the preparation of magnetite nanoparticles and their composites through the electrochemical method and the scale-up method are discussed.

“…Typically, iron is made the anode while the electrolyte consists of mixture of salt and stabilizer. This method has been used by many authors (Cabrera et al 2008;Starowicz et al 2011;Rodríguez-López et al 2012;Kazeminezhad and Mosivand 2014;Yu et al 2014) to synthesize magnetite nanoparticles of well-defined characteristics. Moreover, it has been reported that the distance between the anode and cathode as well as optimized low potential favors the formation of magnetite nanoparticles without metallic iron impurity (Cabrera et al 2008;Starowicz et al 2011;Rodríguez-López et al 2012).…”

Specially designed functionalized nanomaterials such as superparamagnetic iron oxide, gold, quantum dots and up- and down-conversion lanthanide series nanoparticles have consistently and completely revolutionized the biomedical environment over the past few years due to their specially inferring properties, such as specific drug delivery, plasmonic effect, optical and imaging properties, therapeutic thermal energy productionand excellent irresistible cellular penetration. These properties have been used to improve many existing disease treatment modalities and have led to the development of better therapeutic approaches for the advancement of the treatment of critical human diseases, such as cancers and related malaise. In photodynamic therapy, for example, where the delivery of therapeutic agents should ideally avoid toxicity on nearby healthy cells, superparamagnetic iron oxide nanoparticles have been shown to be capable of making photodynamic therapy (PDT) prodrugs and their associative targeting moieties tumor-specific via their unique response to an external magnetic fields. In this review, the nanomaterials commonly employed for the enhancement of photodynamic therapy are discussed. The review further describes the various methods of synthesis and characterization of these nanomaterials and highlights challenges for improving the efficacy of PDT in the future.
