“…Their capability of being manipulated under an external magnetic field provides controllable means of magnetically tagging biomolecules, effective bioseparation, and biosensing, magnetic resonance imaging (MRI) contrast enhancement, and targeted drug delivery [2,3]. In addition, response to an alternating magnetic field allows the transfer of magnetic energy to the particles in the form of heat, opening the opportunity of being used as an important approach to successful cancer therapy [4].…”

A stable oil-in-water (O/W) magnetic emulsion was prepared by the emulsification of organic ferrofluid in an aqueous media, and its theranostic applications were investigated. The synthesis and characterization of the organic ferrofluid were carried out comprising of superparamagnetic maghemite nanoparticles with oleic acid coating stabilized in octane. Both exhibit spherical morphology with a mean size of 6 nm and 200 nm, respectively, as determined by TEM. Thermogravimetric analysis was carried out to determine the chemical composition of the emulsion. The research work described here is novel and elaborates the fabrication of thin-film gradients with 5, 10, 15, and 20 bilayers by layer-by-layer technique using polydimethyl diallyl ammonium chloride (PDAC) and prepared magnetic colloidal particles. The thin-film gradients were characterized for their roughness, morphology, and wettability. The developed gradient films and colloids were explored in magnetic resonance imaging (MRI) and hyperthermia. T1- and T2-weighted images and their corresponding signal intensities were obtained at 1.5 T. A decreasing trend in signal intensities with an increase in nanoparticle concentration in colloids and along the gradient was observed in T2-weighted images. The hyperthermia capability was also evaluated by measuring temperature rise and calculating specific absorption rates (SAR). The SAR of the colloids at 259 kHz, 327 kHz, and 518 kHz were found to be 156 W/g, 255 W/g, and 336 W/g, respectively. The developed magnetic combinatorial thin-film gradients present a significant potential for the future efficient simultaneous diagnostic and therapeutic bioapplications.

Most therapeutic agents for cancer are currently suffering from the shortcomings of poor solubility, severe side effects, and multidrug resistance. Supramolecular self‐assembly (SSA) in nanomedicines is a promising way to overcome these obstacles due to the distinguished properties of noncovalent self‐assembly such as functional diversity, easy stimulus‐response, high biocompatibility, and biodegradability. Moreover, it is more potential to transform them from lab to clinic. In this review, based on lots of state‐of‐the‐art studies, a summary is presented about the recent advances in SSA for cancer treatment, with the introduction of noncovalent driving forces, classifications, design, and applications of multifunctional self‐assembled nanoparticles (SANPs). Finally, the prospects of SANPs on both developing drugs and clinical transformation are discussed.

This article presents the synthesizing of nickel ferrite by sol‐gel modified ionic coordination reaction technique with application in millimetric wave Ferrite Powder Resonator Antenna device fed by a coaxial probe. The ferrite powder was morphologically characterized by X‐rays diffraction, energy dispersive X‐Ray spectrometer, and scanning electron microscopic image; hysteresis loop was also obtained to analyze static magnetic field application and powder's electrical characterization was performed. Ferrite powder electric characterization displayed consistent data, including a material resonance phenomenon around 7.4 GHz. The ferrite powder resonator antenna was designed according to IEEE 802.11a/n protocol and, at resonance frequency around 2.8 GHz, the reflection coefficient results presented a noninfluence of wood material in antenna response, along with a good agreement between experimental and simulated results, reaching a maximum relative error of 1.82%, indicating a promising application of ferrite powder as a resonator.
