“…As the ferromagnetic nanoparticles are suspended in a host fluid like water, they can easily form particle chains under the application of external magnetic fields [134][135][136], thus yielding a magnetic-field-induced anisotropical structure. Recently, a nonmagnetic golden shell was used to enhance the stability of the ferromagnetic nanoparticle against air and moisture [137]. Below we shall show that the effective nonlinear optical response of the suspension which contains ferromagnetic nanoparticles with metallic nonlinear shells (see Fig.…”

We review recent theoretical progress in understanding physical processes of composite effects on enhanced third-order nonlinear optical responses of various kinds of the recently-proposed nonlinear optical materials, namely, colloidal nanocrystals with inhomogeneous metallodielectric particles or a graded-index host, metallic films with inhomogeneous microstructures adjusted by ion doping or temperature gradient, composites with compositional gradation or graded particles, and magneto-controlled ferrofluidbased nonlinear optical materials.

Recently, a non-magnetic golden shell was used to enhance the stability of the ferromagnetic nanoparticle against air and moisture [8]. In this work, we shall show that the effective nonlinear optical response of the ferrofluid that contains ferromagnetic nanoparticles with metallic nonlinear shells can be enhanced significantly due to the effect of the magneticfield-induced anisotropy.…”

Glioblastoma multiforme (GBM) is the most common and most aggressive malignant primary brain tumor in humans. Current GBM treatment includes surgery, radiation therapy, and chemotherapy, sometimes supplemented with novel therapies. Despite recent advances, survival of GBM patients remains poor. Major challenges in GBM treatment are drug delivery across the blood–brain barrier, restriction of damage to healthy brain tissues, and limitation of resistance to therapies. This article reviews recent advances in the application of magnetic nanoparticles (MNPs), gold nanorods (GNRs), and carbon nanotubes (CNTs) for hyperthermia ablation of GBM. First, the article introduces GBM, its current treatment, and hyperthermia as a potential modality for the management of GBM. Second, it introduces MNPs, GNRs, and CNTs as inorganic agents to induce hyperthermia in GBM. Third, it discusses different methodologies for synthesis of each inorganic agent. Finally, it reviews in vitro and in vivo studies in which MNPs, GNRs, and CNTs have been applied for hyperthermia ablation and drug delivery in GBM.
